This work deals with numerical and experimental studies of specific issues of natural convection flow around a horizontal cylinder in a space limited by rectangular cavity. Physical models of laminar unsteady flows have been used for numerical calculations of heat transfer coefficients of four different diameters of horizontal cylinders and for several temperature gradients. Procedures and resu...

Laminar natural convection flow and heat transfer of a viscous incompressible fluid confined between two long vertical wavy walls has been analysed taking the fluid properties constant and variable. In particular, attention is restricted to estimate the effects of viscous dissipation and wall waviness on the flow and heat transfer characteristics. Use has been made of a llnearlzatlon technique ...

The paper is devoted to the study of formation stratification in an incompressible fluid due convective laminar flows horizontal layers heated from side. Medium and intensive modes stationary thermal, concentrational thermo-concentrational (in particular thermohaline) convection are considered, which nonlinear flow features manifested, can radically change structure characteristics heat mass tr...
