Abstract: To guarantee smooth running of a vehicle under the factor load conditions, cooling systems have to perform effectively. The coolant traces the engine block absorbs the heat, when streamed through the radiator loses heat to surrounding. This is a cyclic process and coolant is circulated in a closed loop in the engine block and radiator. Computational fluid dynamics (CFD) analysis is performed in ANSYS fluent to analyze heat transfer process. Geometric model of a 55hp engine radiator was considered and geometric model was designed in CREO. Comparative study between straight and helical tubes was performed considering varying mass flow rates of coolants. Further analyses were performed by varying coolants from conventional fluids air, water to Nano-fluids with different volume fractions. Temperature distributions, heat transfer coefficient, pressure distributions in the radiator are reported in the present work.
