Abstract
An evaporation of
kerosene and water was investigated based on convective heat transfer in the
experimental setup simulating a typical volume of the fuel tank of the launch
vehicle. Basic criteria of similarity used in choosing the design parameters of
the setup, parameters of the coolant and model liquids, were numbers of
Reynolds, Prandtl, Biot, and Nusselt. The used coolants were gases, including
air and nitrogen; in addition, at the stage of preliminary experiments,
products of combustion of hydroxyl-terminated polybutadiene (HTPB) were
considered. Boundary conditions were taken for the liquid located on the plate
in the form of "drop" and at its uniform film spread in the experimental
model setup. On the basis of experimental investigations, the temperature
values were obtained for the system "gas-liquid-wall", and areas of
mass transfer surface and heat transfer coefficients of “gas-liquid” and “gas-
plate” were determined for coolants (air and nitrogen) and for liquids (water
and kerosene). The comparative analysis of the obtained results and the known
data was carried out. Proposals for experiments using coolants based on HTPB
combustion products have been formulated.
