Numerical Simulation of Temperature Stratification in an Accumulation-Type Solar Water-Heating Installation

Numerical study of nonstationary three-dimensional laminar convection is performed in the model of the main element of a solar water-heating installation of the accumulation type in the process of a daily cycle of heat supply. Three-dimensional velocity fields and peculiarities of temperature distributions in the tubular element of installation that are connected with formation of temperature stratification are analyzed at different angles of the element inclination to the horizon.
