Basis of the design model

Because the non-Newtonian behaviour is being taken into account, the equations for momentum continuity and energy respectively, take the form  [Pg.206]

It is important to note that the temperature dependency of the viscosity has a strong influence on the computational strategy and this has an important effect on how the equations should be solved [9]. [Pg.206]

The system is clearly highly non-linear and, in order to obtain a converged solution, it is necessary to solve the problem initially without considering the buoyancy effect, i.e. the term (PoOi T—Tq)) of equation (6.1) is neglected. This [Pg.206]

Power (n) Model Maximum temperature rc) Average temperature ( C) Maximum shear stress (m/s ) [Pg.209]

The temperature distribution is also affected by the height of the impeller above the base and results of this study suggest that it should be at the mid-height position and not the commonly used value of one third the height. [Pg.210]
