A study plan to investigate the effect of the radiator size, orientation of sub cooled section and fan position on Twin fan cooling pack system and to optimize the cooling pack performance for various markets in steady state and transient conditions for off-road vehicle.1D modeling methodology considered with different sub-systems such as coolant, transmission, Engine oil circuit, intercooler, cabin heater/fuel burn heater and condenser, and other components such as thermostats, radiators, fans and pumps etc. GT-SUITE one-dimensional fluid dynamics, used to predict flow behavior and heat transfer characteristics in entire piping network and in other heat exchanging components of a cooling system. A preprocessing tool called COOL3D which is a inbuilt package of GT-SUITE used to build the 3D underhood thermal management models of vehicles, constructing it component by component and therefore allowing including much more details than a usual 1D simulation model. Cooling system performance is predicted in terms of SAT-Safe Ambient Temperature on radiator top hose, Engine Oil EOC Inlet (Sump) and Transmission Oil TOC Inlet which is used to compare different configurations of cooling pack. GT-SUITE object-based code helps us to build reliable cooling system and optimize the cooling pack performance for various market conditions such as Hot, Cold and Standard market and reduces our effort on real time testing.
