Optical measurement techniques from Dantec Dynamics help the Apex Group optimize heat exchangers for energy and cost efficiency

In particular, the Apex Group engineers are interested in the transition process from a laminar to a turbulent gas flow in wide aspect ratio rectangular channels with different inlet geometries. This process was still not fully studied for rectangular channels. By measuring in different channel geometries with optical techniques provided by Dantec Dynamics, the Apex Group has analyzed and studied this phenomena.

The results of the comprehensive study are published in Experimental Thermal and Fluid Science: “Analysis of the isothermal transition process in wide aspect ratio rectangular channels“ by Laurentiu Moruz, Jens Kitzhofer, David Hess and Mircea Dinulescu.
