The analysis of the conservative and non-conservative thermals on the
inclined boundary with a constant slope is carried out. The numerical model
used is the standard 
turbulence model in which the
effect of the density stratification is taken into consideration. The partial
differential equations are discretized by the SIMPLE method proposed by
Patanker. The saline inclined thermals are analyzed as an example of the
conservative case. The turbid inclined thermals in which fine solid particles
are suspended in water are analyzed as an example of the non-conservative
case. The concentration contours and the velocity vectors are obtained using
the numerical results. They show us the flow characteristics of the inclined
thermals in detail. The variations of the travel speed, the maximum thickness,
the maximum concentration in a thermal and the total negative buoyancy in a
thermal are calculated and are compared with our experimental results obtained
before. Reasonable agreements are obtained for both of the saline and the
turbid inclined thermals.
