General Information
1. The objective of the simulation:- Main objective of CFD analysis is following
a. Comparison of inlet and outlet velocity of fluid in Rectangular pipe.
b. Comparison of inlet and outlet presser of fluid in Rectangular pipe.
c. To show the streamline flow in Rectangular pipe in different position like fluid, solid, or
all domain.
d. To show the Contour flow in Rectangular pipe
e. To show the Velocity vector in Rectangular pipe
f. To produce a standard computational fluid dynamics simulation of a vehicle model and to
withdraw relevant data’s.
g. To produce standard of CFD simulations result of drag phenomenon to two cars that are
following eachother. (A., 1996)
2. Introduction to CFD:-
 Civil Engineering Applications: - Rehology of rivers, estuaries, lakes etc. problems are
also the major subject the need to be investigated through CFD. One of the example is the
pumping of mud from an underwater mud capture reservoir. Here, a layer of water sits on
top of a layer of mud, and portion of mud is trapped and is being sucked away at the
bottom. CFD is capable of calculating the velocity field of both mud and water at any
instant
 Environmental Engineering Applications:- CFD gets involved while designing the
building in accordance the heating, air conditioning and general air circulation.
 Naval Architecture Applications-Submarine: - CFD acts as a major source to solve the
hydrodynamic problems that gets encounter with ships, submarines, etc. (K.J., 2001)
3. CFD in Automobile and Engine Applications.
Automobile industries has thrown its hat in the research field associated with the high technology
inordewr to improve the performance of their vehicles. For the same context, they are employing

CFD for the better conceptions of the flow processes and improving the design with the better
substitute. (Bhise, 2017)
Methodology
Step1. Make the 3d Module in the Cad software (Creo, Catia, Solid work, Unigraphix, or any
another cad software) according to given dimension then it convert into .IGS or .STP file.
