A gas wave ejector (GWE) is an efficient energy conversion technology. This study
innovatively proposes a new type of curved diverging channel (Sp-ch channel) and performs …

This paper presents results of investigations focused on a pressure wave exchanger
demonstrator, constructed at the Aerodynamics Division at Warsaw University of …

An optimized wave rotor refrigerator (WRR) that can convert part of the expansion work into
shaft work to improve the refrigeration performance is obtained by the optimization method …

Radial gas wave refrigerators uniquely integrate pressurization and refrigeration processes.
This paper emphasizes optimizing the device's structure to reduce power consumption. It is …

Non-equilibrium phase transition will take place in the pressure oscillation tube if the intake
of wave rotor refrigerator (WRR) contains condensable components, which will affect …

The port width and the offset between them are important structure parameters of a wave
rotor refrigerator (WRR). The arrangement of ports decides the wave diagram in the wave …

This paper adapted and extended the preliminary two-step wave rotor design method with
another step of experimental validation so that it became a self-validating wave rotor design …

There are not only expansion waves, but also shock waves in wave rotor refrigerator (WRR)
channels that usual considered to eliminate as far as possible in the past. Recognizing the …

This work presents an experimental and numerical investigation of premixed flame
propagation in a constant volume rectangular channel with an aspect ratio of six (6) that …

A wave rotor is a shock-driven pressure exchange device that, while relatively rarely studied
or indeed, employed, offers significant potential efficiency gains in a variety of applications …
