Heat transfer investigations are essential to continually develop advanced heat exchangers and HVAC&R systems. Conventional techniques provide limited insights on the performance of advanced heat exchanger designs and can be limiting in exploring the full potential of new surfaces or channel geometries. This seminar presents two innovative techniques to investigate the heat transfer and pressure drop in advanced heat exchangers. The first covers the use of neutron imaging to visualize the two-phase flow in diabetic flow inside microchannel heat exchanger tubes. The second describes development of a cost-effective and compact multipass manifold microchannel heat and mass exchanger for HVAC applications.
