Transient flow through a Throttle Body
This transient flow is carried out by rotating the throttle valve by 25 degree from its open position during the simulation. The rotation of throttlr valve happens between 0 to 2 milliseconds.
The Flow is carried out for 10 milliseconds.
The base mesh size is 2e-3 in X, Y, Z direction. Opted for fixed embedding near the throttle valve. The scale of embedding is 3 and number of layers are 2.
The minimum time step is 1e-6 and maximum is 1 second.
The turbulence model used in RNG K epsilon.
