Heat Transfer in Internal Combustion Engines
A heat transfer model has been developed that uses quasi-steady heat flux relations to calculate the heat transfer from combustion gases through the cylinder wall to the coolant in an internal combustion engine. The treatment of convective heat transfer accounts for the physical problems of rotating and impinging axial flow inside the engine cylinder. The radiative heat transfer includes gas ra...
متن کاملRadiation Heat Transfer in Combustion Systems
An adequate treatment of thermal radiation heat transfer is essential to a mathematical model of the combustion process or to a design of a combustion system. This paper reviews the fundamentals of radiation heat transfer and some recent progress in its modeling in combustion systems. Topics covered include radiative properties of combustion products and their modeling and methods of solving th...
متن کاملHeat transfer during impact
The amount of heat transferred by conduction during the impact of a spherical particle with a surface depends on the thermophysical and mechanical properties of the two colliding media. Other factors, such as the surface properties (e.g. roughness, contamination, stress state, radius of curvature) and the velocity and direction of the impact, also influence the heat transfer. The available theo...
متن کاملComputational Study of Radiative and Convective Heat Transfer in a Cylindrical Combustion Chamber
In this paper, the effect of cold air on the fluid flow inside the cylindrical combustion chamber and its wall temperature distribution have been studied computationally, taking into account the effect of radiative heat transfer from hot gases. The results have been compared with the case that radiative heat transfer was neglected. It is observed that the reattachment length increases when incr...
متن کاملExperimental Investigation of Thermal Balance and Valve Cover Heat Transfer in a Small Internal Combustion Engine
Heat transfer in internal combustion engines is one of the most significant topics. Heat transfer may take place through thermal conduction and thermal convection in spark ignition engines. In this study, valve cover heat transfer and thermal balance of an air-cooled engine are investigated experimentally. The thermal balance analysis is a useful method to determine energy distribution and effi...
