Introduction
Fluid dynamics is a study that is interesting and challenging in equal measure, since fields are every
where in the practical world, we are living in. Therefore, fluid dynamics is needed to study the flow of
fluid. There are three physical laws that can describe or solve the fluid flow, actually they are equations:
 Mass conservation: Continuity equation
 Momentum conservation: Momentum equation, the second law of Newton
 Energy conservation: Energy equation, the first law of thermodynamics
The philosophies described above shows that mass, momentum, and energy are steady constants in a
system that is closed.
We shall now describe what Computational Fluid Dynamics (CFD) is, which are numerical methods that
are applied to get approximate solutions for the heat transfer and fluid dynamics. CFD is an approach that
is very powerful that covers a vast range application that are industrial and non-industrial. Ansys CFD
and Twin-Mesh are used for; innovative and better designs to be able to understand the complex
techniques, and flexibility at cost reduction and a fast at virtual prototyping.
Methodology of simulating a screw compressor
A group of meshing helical screws rotors are contained in the screw compressor container/housing. There
are rotors which have their profile on the outer side of the pitch circle, these are called main rotors or
male rotors. Yet the ones with their profile into the pitch circle are known as the gate or female rotors.
The screw compressors have the main components in gears, and bearings among other components,
which needs to be lubricated by either isolating the shafts seals the applying the lubricants also at the
compressions chamber, and normal lubrication (Mathu, 2016).
Here, there shall be a description of the use of Ansys in solving problems, they are like the following:
