A solar-driven Stirling engine is modelled as a combined system which consists of a solar collector and a Stirling engine. The performance of the system is investigated, based on the linearized heat loss model of the solar collector and the irreverisible cycle model of the Stirling engine affected by finite-rate heat transfer and regenerative losses. The maximum efficiency of the system and the...

A lumped parameter model is developed to study performance of marine diesel engine thermal management system. One dimensional flow equations combined with classical Webie combustion model and Woschni heat transfer model are employed to describe diesel’s flow characteristic. Modeling results of heat release from diesel engine is validated against experimental data. Cooperated with experimental d...

In case of automobile the fuel saving is the prime important with minimum emission and best performance. The phenomenon by which heat transfer takes place through engine fins must frequently be improved for these reasons. Air-cooling used to reduced weight and simple in construction of engine cylinder block. So,air-cooled engine build heat, the cooling fins permit the wind and air to move the h...

We show how the Yarkovsky effect can be understood as a heat engine. The output of the engine, manifested in the rate of change in semimajor axis of the body, has a maximum at an intermediate heat capacity, depending on the rotation rate of the body. This maximum arises because the work output depends on the product of the solar heat absorbed by the body and transported from its morning to even...
