Control of multiple-passage cannel flows using DBD plasma actuator

Nihon Kikai Gakkai ronbunshu, 2014
Inside of fuel cells, heat exchanger, chemical reactors, and other industrial devices, the fluid flow comes into the inlet chamber and streams into many branch passages. A uniform flow distribution requirement is a common issue in those devices.

Pressure loss prediction of gaseous flow in a conduit-system of microchannel heat exchanger

Nihon Kikai Gakkai ronbunshu, 2020
Three methods for predicting pressure loss of gaseous flow in a conduit-system of microchannel heat exchanger are proposed and discussed. In the experiment, the heat transfer plate which is the core of the heat exchanger has 34 rectangular microchannels.

Loss of Height Pressure in a Layer of Granular Materials

The Annals of “Dunarea de Jos” University of Galati. Fascicle IX, Metallurgy and Materials Science, 2019
During the air blown in the furnace, from the vents to the loading mouth, the gases lost from the initial pressure depend on several factors, such as the care and the granulation mixed with ores and coke from the layers of care.

Intraoperative Collection of Ascitic Fluid With Intra‐ or Postoperative Reinfusion in Ovarian Cancer: Safety and Feasibility of a Roller Pumping Method

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Patients with ovarian cancer often present with massive ascites, leading to significant protein loss during surgical procedures. Although cell‐free concentrated ascites reinfusion therapy (CART) is used in palliative settings to mitigate protein loss, its application in intraoperative settings remains unexplored.
