Perspective Study of Fluid Dynamics towards Engineering Students: A Short Review

In this paper we will deal about the importance of the study of the subject Fluid Dynamics in Engineering field. Students are more likely to study Engineering courses in the recent days. Engineering deals with the basic concepts of Mathematics, Physics and Chemistry. Though, Computer Science subject is a pulse to Engineering, the subjects, Mathematics, Physics and Chemistry are heart beat to Engineering courses. In this study, we will discuss where and how Fluid Dynamics stands as a crown to Engineering Field.


Students and Fluid Dynamics:
A student studies Physics and Mathematics for almost five to seven years at his school level and when he graduates to his college life, Physics is considered as the optional subject when he studies Arts and Science Courses, but Mathematics will be a mandatory subject in atleast any one of the semesters. A student who choose Mathematics as his major discipline in his/her college life, will completely learn moreover all the field areas in Mathematics. Definitely, a Mathematics student has this subject knowledge in various fields of Mathematics like Differential Calculus, Integral Calculus, Probability and Statistics, Operations Research, Graph Theory, Partial Differential Equations, Numerical Methods, Real Analysis, Complex Analysis, Operator Theory, Topology, Fluid Dynamics, Control Theory and even more fields. Among the above said topics of study, a student can get through just if he has the mathematical knowledge and interest. There is a paper named Fluid Dynamics (Spurk, J, 1997), which as the name referres, it can't be dealt that it is completely Mathematics. Right from the school level of study, a student who is well interested in both Physics and Mathematics can feel the paper light and crack it easily (Pietro Vishia, 2020). Fluid Dynamics comprises of the concepts of Physics topics and it can be solved only by mathematical knowledge where starting from the fluid, a combination of liquid and gases flows, it relates to the temperature, pressure, study of the movement of the particles, implicating to Initial value problems, Boundary value problems involving the concepts of Differentiation and Numerical Methods of solving problems (Munson, B.R., Young, D.F., and Okiishi,T.H., Huebsch, W.W, 2009). When specifically, a student is interested to learn these concepts, a student opts to enters the research field to study more and discover the concepts.
But when a student gets an Engineering course whatever, the branch of Engineering may be definitely a student studies Physics and Chemistry for atleast one semester and Mathematics minimum for upto four semesters at his course of his study. It is not a pride, that the Mathematics is an unavoidable subject, rather than a student must realize the need of the subject and its importance towards the subject in their course of study.

Need of Fluid Dynamics in Engineering Branches:
A student when opts to study any of the Engineering branch, a student studies Physics along with the Mathematical concepts and Mathematics along with the Physical Science concepts (Ashwin Vaidya, 2020). This is an argument that no student can while away Physics and Mathematics for their semesters. Here, our point of view is, where does the Physics and Mathematics subject Fluid Dynamics applies in. This is a subject related to both Engineers and Physicists. All branches of Engineering such as Aerospace, Civil, Pollution Control, Mechanical, Mechatronics and Chemical Engineering uses Fluid Dynamics widely and mostly. Fluid Dynamics needs both Physics application and mathematical analyses knowledge.
Apart from the above said branches, there are more branches of Engineering which uses Fluid Dynamics. The branches like Electronics and Communication, Electrical and Electronics, Computer Science, Information Technology also uses Fluid Dynamics. This application where they are using are known to the academicians and teachers, but this must be brought to the knowledge of the students regarding what field is this. What are the topics, a student studies in Fluid Dynamics (White, F) must be briefed to the students, then only student will know the importance of it. In any of the semester, definitely a student studies Fluid Dynamics in the name of the Vector Calculus. Vector Calculus is one of the major and unavoidable topics either in the first or second semester  In this article, we have also discussed shortly about the Fluid Dynamics study to the Mechanical Engineering and to the Civil Engineering branches.

Fluid Dynamics in Mechanical Engineering:
Generally, the students those who opt to study Mechanical Engineering will be really practical experiments interest oriented. These students always think about Machines, working of models, experiments and development for further improvements. For a model to work out for a sample machine, the student must have the knowledge of Fluid Dynamics which is the study which relates to the motion of the objects. Mechanical Engineering studying students will have a paper definitely like Engineering Mechanics or Applied Mechanics (Covel . L. Brunton., Bernd R. Noack., Petros Koumontsakos, 2020) in their branch of study as it forms the base to their course and for further studying of the course.
They must have a strong base in Fluid Dynamics as it accounts for the improvement of the study related to turbines, heat exchangers, fluid flow, fluid cooling, hydrostatics, calculating pressure, buoyancy force of fluids which acts on objects in stationary mode, transportation of ships, force acting on tanks and dams. To different atmospheric conditions to be dealt, Fluid Dynamics plays a vital role. When the student understands the concept of Fluid Dynamics, which is a branch of Fluid Mechanics, the student will definitely have an opportunity to build the concepts and apply it practically for the problem to be solved in real time applications with the good engineering dealt with problem solving skill. Whatever, a technology to be invented by a Mechanical student, Fluid Dynamics study is mandatory starting from the building of a small motor (Hongyun Wong 2006). In the design of aircrafts, cars, Fluid Dynamics plays a significant value of role and many more future mechanical inventions.

Fluid Dynamics in Civil Engineering:
Fluid Dynamics in Civil Engineering is really a vein to the course. Students studying Civil Engineering will be really very well interested in practical constructions and almost in the building of the huge empire of the world. This development will be like a nightmare in Civil Engineering without Fluid Dynamics. Everyday, Fluid Dynamics is adding feather to its cap by launching its capability in Civil Engineering (Durst, F, 2008). A Civil Engineering student must be well taught with the concepts of Vector Calculus, which is in turn Fluid Mechanics (Dynamics). The Fluid Dynamists always does not think in the way of Mathematicians, but they must think like the builders. Many industrial based problems are solved using Civil Engineering concepts, moreover it is mandatory for first of all the industry architecture to be built. Each building starting from a pillar is purely Fluid Dynamics (James. M. Wallace, 2016). A Civil Engineer constructs irrigation canals, dams, water supply chain system, reservoirs, sewage treatment plants, water treatment systems, purification of water, building of turbines, manufacturing of pumps, calves and pipes, coastal engineering, construction of skyscrapers, storage of liquids in tanks, capacity of toleration of wind at the top areas of buildings, pollution control, fire extinguishers, air conditioning, ventilation and heating facilities in a building, transportation of gases are the places where fluid Dynamics applications are unavoidable. This is really a boon to the field. Students must be made aware of it, because Fluid Dynamics takes its place from our home, the place where we live in. Without Fluid Dynamics, there is no Civil Engineering is quietly acceptable.

Conclusions
The purely application oriented Fluid Dynamics paper has been taught to the Engineering students in the name of the Vector Calculus and it must be made aware to the students, the field what they are studying the teachers and the academic experts and make them know the importance of it and the name of the stream through their teaching and applications. This first work of initiation will pave many more inventions fruitfully in the future research area of Fluid Dynamics and also to the development of this study as every drop only builds a huge ocean.
