Tutorial on Air flow through a turbo casing

A turbo in any engine is used to increase the air flow into the cylinders to ensure efficient and complete combustion of the fuel. With a turbo, the efficiency of the engine is increased. Engineers are tasked with designing turbo with optimum efficiency. It is, therefore, important to run the model through simulations to observe how it behaves. I will be simulating flow through the channel of a turbo. It is important to note that the spiraling nature of the geometry optimizes the effects created by the impeller.
My turbo model looks like the one below.

Before we begin the flow simulation we are first required to create lids for both the inlets and outlets. To run the lids functionality we need to first enable the Solidworks to flow simulation add-in.

Using the create lids formula and choosing the surfaces you would want the lids inserted so you can simply create the lids.

Once you have the lids inserted you can proceed to run the flow simulation. Define your project name on the first tab that shows once you run the wizard.

Next, you define the desire units (SI here) and the flow material.

To set up the study, we need to define the boundary conditions at the inlet and outlet. We have the computational fluid domain setup once we start running the analysis.

Set the inlet mass flow rate to 10kg/s and for the outlet set the conditions as atmospheric (Environment pressure)

Once you have defined all your parameters, you can now proceed to run the simulation by right clicking on the project name. Here you can specify the number of iterations you would like to run and the refinement specifications after every iteration.
 
The best thing about SolidWorks is that it automatically generates the mesh making simulation easy.
 

Based on the results from solver we are able to generate cut plots and flow trajectories just like the one shown below
