The combustion process in an intemal combustion engine must be known in detail to ï¬nd out the dependence of its operating conditions on the engines performance. This paper discusses a computer program that simulates the combustion processes of a two-stroke engine. The simulation includes modelling the heat transfers from the cylinder and crankcase, modelling the heat releases for gasoline and diesel engines, modelling the gas properties, modelling the energy balance, and modelling the flow coefficients through the ports. The performance of the two-stroke engine can be obtained from the…
This paper evaluate the elastic ï¬eld that induced by a uniform pressure applied over a circular area on the surface of an elastic half space. The half space is transversely isotropic, where the planes of isotropy are parallel to the surface. A potential function method is adopted where the elastic ï¬eld is written in terms of three harmonic functions. The known point force Green functions are used to ï¬nd the solution for uniform normal load over the area by quadrature. The elastic displacement and stress ï¬eld are evaluated in term of closed form expressions containing complete elliptic…

The thermohydraulic aspect utilization on a nuclear reactor is very dominant, because the system gives limitation on the reactor operation. Regarding the problem, theoretical analysis of thermohydraulic aspect is done for a research reactor of 2 MW with hexagonal conï¬guration of fuel elements With an assumption that the power generation each fuel element is the same and the other facilities are neglected, the output of FLUENT V4.25 program gave information that theoretically this research reactor can be operated on thermal power of 2 MW.
A fluidized bed is a bed comprises a mixture of solid particles suspension in stream of gas. The heat transfer phenomenon between the surface of immersed body to/from fluidized bed is very complicated mechanism. Aside from the governing variables on conventional convective heal transfer, the rate of heat transfer coefficient in fluidized bed, is also influenced by physical and geometrical properties of solid particle. One of the variables which governs the value of thermal convective heat transfer coeï¬icient is voidage. The influence of voidage on thermal convective heat transfer…
