摘要

It has been carried out a study on natural convection in a vertical fluid layer of water with uniform internal heat generation. Fluid layer was rectangular confined regime. A pair of opposite vertical walls were cooled and maintained at constant temperatures respectively, and other boundaries were adiabatic. Flow visualization was conducted with tracer method and ink-injection method. Temperature distribution was also obtained. Flow pattern changes systematically with external and internal heating rate. Flow patterns were classified into three types with the internal and external Rayleigh numbers. Similar flow patterns were observed for several aspect ratios. For large Rayleigh number, unstable wavy flow was observed. Numerical calculations were also conducted in stable case.
