Abstract:
Flow characteristics and heat transfer of refrigerant R134a that pass through
the inside of the evaporator were analyzed. In recent practical heat exchangers, the
grooves engraved on the heat transfer surface are introduced to increase the heat
transfer area. The influence of the cross-sectional shape of fine grooves on the boiling
phenomenon of the refrigerant was experimentally examined by flow visualization and
heat transfer measurement in this study. The separation of bubbles from the heat
transfer surface and the inflow of liquid refrigerant to the fine groove affects heat
transfer enhancement. A rectangular concave fine groove path was set on the heat
transfer surface in this study. The dimensions of the groove path were set to a groove
width of 0.8 mm, a groove depth of 0.4 mm, and a length of 100 mm with reference to
apply to an actual evaporator. The heat transfer surface is set with a constant heat flux.
In the visualization of the refrigerant two-phase flow, the generation and growth of
bubbles were observed by high-speed camera. In addition, the local heat transfer
coefficient was simultaneously estimated, and the correlation between the flow
transition of refrigerant gas-liquid two-phase flow and the heat transfer enhancement
was analyzed.
