“…They concluded that the Beale number for a LTD Stirling engine could be found from the mean-pressure power formula. Kongtragool and Wongwises [6] (2005) investigated, theoretically, the power output of the gamma-configuration LTD Stirling engine. The former works on Stirling-engine power output calculation were studied and discussed.…”

NWaste heat is that heat which is generate in a process by way of fuel combustion or chemical reaction, and then dumped into the environment even though it could still be reused for some useful and economic purpose. There exist today worldwide concerns about the best ways of using the deployable sources of energy, and of developing techniques to reduce pollution. This interest has encouraged research and development for re-use of the usually wasted forms of energy. There are many methods through which waste heat energy can be recovered and utilized. Stirling engines are mechanical devices working theoretically on the Stirling cycle. It uses air, hydrogen, helium, nitrogen or even vapors as working fluids. The Stirling engine offers possibility for having high efficiency engine with less or zero exhaust emissions in comparison with the internal combustion engine. We manufactured a gamma type Stirling engine which operates at low temperature differences.

-In this paper, a 1-D model of an half alpha type ''double-acting'' Stirling engine (made up of two doubleacting pistons, two hot heat-exchangers, two cold heat-exchangers and a common recuperator-regenerator for the two separate gas circuits, all that giving two cycles with 180°phasing) is presented. In this architecture, two cylinders, containing, each one, a double-acting piston, are combined in order to operate like two parallel Stirling systems in opposition of phase. This model, derived from Andersen's model, is used to describe the compressible flows in the half-engine, under energy transfers. A finite-volume numerical method is applied for the equations of energy, mass and momentum assessment. This modelling was carried out using the Matlab/Simulink software. The results of this dynamic modelling relate to one half engine. We obtain the evolution of the physical parameters (density, pressure and temperature), and the (p, V) cycle. The influence of the various assumptions was studied. A parametric study was carried out in order to obtain the optimal values of the geometry of the engine and its ideal speed of operation.

“…As a result, its use is traditionally considered difficult to justify [19,20]. Beale offers an expression for the engine power output in terms of mean cycle pressure, power piston swept volume and operating frequency [21]. Analyses based on the ideal cycle are typically described as zero order as well [19].…”
