Summary

NUMERICAL SOLUTIONS INDICATE THAT THE TEMPERATURE-DEPENDENT VISCOSITY STABILIZES THE FLOW ALONG A HEATED WALL AND DESTABILIZES IT ALONG A COOLED WALL. THE TEMPERATURE-DEPENDENT COEFFICIENT OF THERMAL EXPANSION INITIALLY STABILIZES THE FLOW FOR A HEATED WALL BUT FARTHER DOWNSTREAM IT DESTABILIZES THE FLOW. FLOW VISUALIZATION STUDIES IN WATER WITH AN ISOTHERMAL, VERTICAL COPPER PIPE SUPPORT THE NUMERICAL PREDICTIONS.
