The Experimental Study on Performance of Single Screw Expander with Air as Working Fluid
Advanced Materials Research, 2013A new single screw expansion machine was developed in order to improve the practical level of low temperature thermal power generation technology and the utilization of waste heat and renewable energy. With compressed air as working fluid, the power, efficiency, gas consumption rate and temperature difference of single screw expander with rotational ...

Improving thermodynamic efficiency of prime movers is the key issue for efficient utilization of low temperature heat resources. Because of many good characteristics, the single screw expander is perhaps a good choice. Precisions in manufacture and assembly are very important factors to the performance of single screw expanders.

Journal of Hydrodynamics, 2014
The CFD simulations are carried out for the flows in a horizontally oriented helical pipe with various inlet sectional liquid holdups and coil pitches (H). The development of the pressure fields for the single phase air flow and the air-water two-phase flow through the helical rectangular channels is studied.

Static Finite Element Analysis on Cast Shell of a 100 kW Single Screw Expander
Applied Mechanics and Materials, 2014In the process of shell design of a 100kW single screw expander, the fundamental research on the screw chamber walls thickness is still lacking. Thin wall may cause deformation and the damage possibility of the inlet passage. Thick wall will increase the weight of the expander and led to assembly problem and transportation inconvenience. In this paper,

Power system study of engine waste heat recovery based on single screw expander
2011 International Conference on Electric Information and Control Engineering, 2011This paper introduces the principle of the engine waste heat recovery system. The organic Rankine cycle (orc) system is proposed to improve the efficiency of waste heat recovery. GT-power software is used to make a DI engine model of 493ZLQ3. The model simulates the exhaust temperature on the brake power curve and brake torque curve based on the ...
