MIXING EFFICIENCY Performing steady-state simulations to compare the mixing effectiveness when the hot inlet temperature is 36C(309.15K) and 19C(292.15) are entrained from the X-Axis and Y-Axis respectively. We will also determine what is the effect of changing the momentum ratio. Also, different turbulence models(K-Epsilon…

Steady Vs Unsteady flow over a cylinder
STEADY VS UNSTEADY FLOW OVER A CYLINDER The aim is to simulate the flow over a cylinder for both steady-state and transient cases and observe the Von Karman Vortex Street. Von Karman Vortex street is a repeating pattern of swirling vortices caused by a process known as vortex shedding which is responsible for the unsteady…

BRAKING ENERGY,BRAKING STRATEGY AND MOTOR LOSSES
1) BRAKING ENERGY A significant amount of energy is consumed in braking. To stop a car entirely, the kinetic energy of the moving vehicle has to be absorbed. Braking power and braking energy consumed by the front and rear wheels are closely related to the braking forces on the front and rear wheels. Ignoring the…
