ITU Dept. of Mech. Eng. Heat and Mass Transfer Laboratory is basically a research laboratory where heat and mass transfer experiments are carried out in a porous medium. Experiments in oscillating and pulsating flow are also carried out in the laboratory. Analytical methods and numerical solutions, which are theoretical approaches, are also applied to all kinds of heat, mass and momentum transfer problems. Two-phase flows are also studied. As well as the thermal conductivity and total heat transfer coefficient measurement experiments that contribute to the industry, services such as consultancy, expert and project supervision are also provided in line with the needs of the Turkish Industry.

 Topics

• Determination of Heat Transfer and Pressure Drop in Porous Media. Packed balls and metal foams are used as porous media in laboratory studies. Time-dependent oscillating and pulsating flows are also being studied. Some sample studies: Determination of heat transfer and pressure drop in spiral packed beds in different curvature diameters, channel widths and porous environments, experimental investigation of heat transfer and pressure drop in case of pulsating air flow in circular cross sectional duct with metal foam inside, experimental investigation of heat transfer and pressure drop in case of pulsed water flow in a rectangular duct with metal foam inside, determination of heat transfer and pressure drop in case of reciprocating water flow in circular cross-section channels containing metal foam with different PPI pore densities.
