Experimental Facilities

Pool Boiling Facility with Multimodal Sensing

Summary: This pool boiling facility is designed to investigate the thermal performance and bubble dynamics during pool boiling of DI water on a variety of surface structures in the nucleate boiling regime and the critical heat flux condition. It enables synchronized multimodal sensing including optical, acoustic, thermal, and pressure signals. The pressure in the boiling chamber is regulated using a coiled copper condenser and a Graham condenser with an external chiller.

Credits: This facility is designed and assembled by Hari Pandey with instructions from Manohar Bongarala at Purdue University.  The boiling chamber was machined by Jeff Knox at Engineering Research Center. The stereo imaging calibration system was set up by Hari following the guidance of Carolina Mira-Hernandez at Universidad Pontificia Bolivariana.
