Calculation of Radial Velocities

This does not mean that h is zero. Instead, it can be calculated from the fluid 

Radial motion of fluid can have a significant, cumulative effect on the convective diffusion equations even when has a negligible effect on the equation of motion for V. Thus Equation 8.45 can give an accurate approximation for even though Equations 8.20 and 8.24 need to be modified to account for radial convection. The extended versions of these equations are 

The boundary conditions are unchanged. The method-of-lines solution continues to use a second-order approximation for da/dr and merely adds a Vr term to the coefficients for the points at r Ar.

Work on the fluid mechanics of radial flow reactors can be traced back to the calculations of radial velocity profiles by Soviet investigators (1,2). This analysis was later repeated by...
