Numerical Modeling of Solar Radiation Heat Transfer for a Truck Cabin

Abstract:

The temperature inside the vehicle cabin will be higher than the outside environment temperature in parked conditions due to radiative effects. This increased temperature is not uniformly spread within the driver cabin due to absorption capacities of the various materials used for construction and the angle of incidence of the incoming radiation. The objective of the work is to predict the accumulation of heat inside the cabin numerically and find hotspots throughout the cabin. The path of the sun in different seasons and timings on a particular location was calculated and is implemented for the angle of incidence of radiation on the cabin. The investigation provides the variations of temperature, transmitted solar radiation and amount of absorption by various components that are subjected to assessment. Thus the major contributing factor for the abrupt increase in temperature was found.
