Effect Of Different Mesh Element Size On The Pressure-valve Model

ABSTRACTThe impact of improvement in vehicle aerodynamics mainly reflects in lower fuel consumption and lower carbon dioxide emissions into the atmosphere. The governments of many countries support continuous aerodynamics’ improvement programs as a way of mitigating the energy crisis and atmospheric pollution. This…
