Abstract
ABSTRACT This work aims to study the laminar film condensation heat transfer with magnetic field effects on a finite-size horizontal wavy disk. Mathematical analysis is used to obtain the dimensionless governing equations and boundary conditions, and the cubic spline collocation method is then used to calculate the flow and heat transfer characteristics along the wavy disk. The effects of the important parameters, such as Hartmann number, condensation parameter, wave number, amplitude-wavelength ratio, and Pr/Ja on the heat transfer characteristics have been successfully examined. The magnetic field effect increases the critical condensate thickness and thus decreases the condensation heat transfer. Odd wave number effects decrease the critical condensate thickness and thus enhance the condensation heat transfer.
