Operating characteristics of thermoacoustic compression based on alternating to direct gas flow conversion

Wang, Kai; Sun, Daming; Xu, Ya; Zou, Jiang; Zhang, Xiaobin - In: Energy 75 (2014) C, pp. 338-348

A thermoacoustic compressor is capable of converting an alternating gas flow to a direct one with a large pumping rate on the basis of the pressure oscillation nature of thermoacoustic engines and the flow rectification effect of check valves. Theoretical calculations are first carried out to...

Experimental study of the performance of a circular tube solar collector with closed-loop oscillating heat-pipe with check valve (CLOHP/CV)

Rittidech, S.; Donmaung, A.; Kumsombut, K. - In: Renewable Energy 34 (2009) 10, pp. 2234-2238

This paper describes the performance of a circular glass tube solar collector with a set of closed-loop oscillating heat-pipes with check valves (CLOHP/CV). The assembly was divided into three sections, i.e. circular glass tube, adiabatic gap and condenser water tank. A circular 10-set glass...
