Description:

Within the framework of the exFan project, experiments are being conducted with this test rig to validate simulations and calculations. Air enters the duct through a bellmouth inlet and is heated by the heat exchanger, which is inclined to the air flow. Temperature, pressure and velocity are measured at various positions. A modular design is intended to provide valuable insights into the interactions between air flow and heat exchangers at different geometries and operating points.
