Prediction of Flow Characteristics of Conservative Two-dimensional Inclined Thermals

Abstract

Flow characteristics of miscible conservative two-dimensional thermals traveling downslopes are investigated theoretically. An integral model is developed, using such empirical relationships as the entrainment function, thermal aspect ratio and others. A set of solutions for a fully developed state is obtained analytically and numerically. Resistance coefficient is determined semi-empirically. Comparisons between calculated and experimental results are presented as well.
