Introduction The objective of this report is to understand the flow over a throttle valve and to practice the mesh refinement using converge tool, also, learning how to give motion to a body and to read the output plots. Mesh Below is the mesh for the throttle body. The mesh is refined around the the valve by the use of…

This report will answer the question of what is Reynolds stress, turbulent viscosity, and molecular viscosity while deriving Reynolds averaged Navier stokes equation by applying Reynolds decomposition to Navier stokes equation.   Reynolds decomposition Consider a sensor measuring velocity in turbulent flow the plot…
