Numerical Simulation on Dynamic Behavior of Waste Heat Recovery Stirling Engine

Numerical Simulation of Beta Type Stirling Engine Considering Heat and Power Losses

In this paper, numerical solution of beta-type Stirling engine was presented considering its non-ideal regenerator. To this end, the second-order model including heat and power losses was used. Then, a numerical code was applied for calculating geometrical and physical optimum values of the engine. To confirm the obtained results, the physical and geometrical parameters of the GPU-3 engine were...

Dynamic Behavior of a Free-Piston Stirling Engine Driven Heat Pump With Magnetic Coupling

A new low-cost design for a free-piston Stirling engi ne driven heat pump is presented. The new approach uses a linear-acting magnetic coupling to transfer engine power across a hermetic shell. Camp l i ance in the coupling affects the performance and stability of the system, especially with regard to matchin g the engine dynamics to the compressor load. This paper first describes test results ...

Waste Heat Recovery Technologies In Turbocharged Automotive Engine – A Review

Significant waste heat recovery technologies have been developed to recover exhaust heat and turn it into useful energy such as in downsizing the engine or to regain the auto-electricity. Extensive work and research in energy recovery have been identified in the automotive sector; therefore the main objective of this paper is to assess each waste heat recovery technology based on current develo...

Dynamic modeling and simulation of an Organic Rankine Cycle (ORC) system for waste heat recovery

The paper proposes two alternative approaches for the design of a dynamic model for an Organic Rankine Cycle (ORC) to be used for the design of control and diagnostics systems. The model has been developed in Modelica language and simulated with Dymola. The two modeling approaches, based on moving boundary and discretization techniques, are compared in terms of accuracy, complexity and simulati...
