Cooling Airflow System Modeling in CFD Using Assumption of Stationary Flow

摘要: Today CFD is an important tool for engineers in the automotive industry who model and simulate fluid flow. For complex field of Under hood Thermal Management, has become a very to engineer cooling airflow process engine bay vehicles. To accurately CFD, it utmost importance all components path accurately. These are heat exchangers, fan blockage effect. This paper presents simulations together with correlating measurements system placed test rig. The contains heavy duty truck louvered fin radiator core, shroud, ring fan. Behind module 1D silhouette mimic done by behind Furthermore simple mounted over air guiding bay. The monitor pressure flow system. Supporting this examination set 48 velocity probes that measures local velocity. correlated measurements. Furthermore support these simulations, specific conducted using only only. This see how well each separate component predicted back work continuation presented [5] identified one can rather steady state CFD. However, modeling sensitive care be taken order accurate.
