Hydrocarbon Liquid

The numerical modeling of the heating of a high-viscosity hydrocarbon liquid, whose viscosity and thermal conductivity depend on the temperature, is carried out in this research. A system of equations for free convection is solved in the linear Boussinesq approximation. The dynamics of changes in the temperature field and convective structures in a liquid is studied.

Velocities in two laminar free convection air flow fields were measured using a laser velocimeter. Velocities were first measured in the boundary layer around a heated vertical flat plate and results compare within two percent of theoretical and previous experimental (streak photography) data. Second, velocities were measured throughout a two-dimensional triangular enclosure, which consisted of two isothermal side walls (one heated and one cooled), an insulated bottom, and glass end plates. Enclosure data are compared to simple inclined isothermal plate data and are also presented so that the flow patterns can be observed.
