... power density, and robustness in high-pressure and/or high-temperature environments. However, the large difference between a compact HX's overall dimensions (∼m) and the much smaller scale of its channels (∼mm) makes it challenging to model the entire HX at once, due to computational limitations...

... to experimentally investigate the effect of flow rate on flow phenomena generated in a multistage Tesla valve. In this investigation, the diodicity of the Tesla valve was considered as a flow parameter and was calculated using point pressure measurement. The change in the diodicity was explained using the flow...

...A. Spaggiari; E. Dragoni Magnetorheological (MR) fluids are widely used in the industrial world; however, sometimes their properties fail to meet system requirements. In shear mode, MR fluids have been found to exhibit a pressure dependency called squeeze strengthen effect. Since a lot of MR fluid...

...B. Prabhakara Rao; Sarit K. Das A detailed experimental study on flow maldistribution from port to channel of a plate heat exchanger is presented. In general, flow maldistribution brings about an increase in pressure drop across the heat exchanger. This increase is found to depend on flow rate...

The obtained results show that the geometry of the reflected wave pattern is similar in the two cases when both incident waves have the same initial pressure jump across their fronts. However, different reflected pressure signatures (history) are observed in these two cases...
