Abstract

The report deals with the computational fluid dynamic (CFD) simulation and analysis of the clothes drying using rejected heat (CDURH) drying compartment. The performance of the drying cabinet is analyzed by observing on the hot air flow and temperature distribution inside the cabinet. From the literature studies, most of the fabric or textile CFD simulations applied the fabric model that had been input to the CFD program by recasting the corresponding governing transport equations. Thus, similar approach is used in this project where the wet fabric drying model is developed by recast the governing equations of the porous medium into the Fluent solver using the user defined function. Validation is performed to the simulation result and fabric model developed is found able to predict the total drying time required for the fabric to be dried to equilibrium condition with percentage errors of 1.3 % and 2.4 % for given conditions. The same model is applied to the actual clothes dryer and CFD simulation is performed. The simulation result is then studied and analyzed to determine the important parameters in designing the clothes dryer.
