Summary

These problems, which are often encountered in honeycomb desiccant wheels, are numerically investigated via the boundary-fitted coordinate system. The control volume-based finite difference technique is applied to obtain the solution using the numerically generated boundary-fitted coordinates. According to this method, the complex domain in the physical plane is transformed into a regular square domain in the computational plane. The effects of aspect ratios and bending ratios of the ducts on the friction coefficients and heat transfer coefficients are studied and graphically illustrated under uniform wall temperature boundary conditions.
