Research
Interests
Convective
heat transfer with and without phase change, heat-transfer augmentation,
heat transfer under microgravity conditions.
Current
research interests are on condensation and phase separation. In-tube
condensation has been extensively used but as yet there is no satisfactory
model to predict the local heat-transfer rates. An experimental
setup is available to determine the heat-transfer rates, interfacial
shear stress, and details of interfacial waves.
A glandless,
rotating device that will permit the separation of the condensate
in condensation and the liquid phase in a liquid-gas mixture as
a possible condenser and phase separator in microgravity condition
is being considered.
