This paper presents numerical analysis that investigates the effect a slip boundary condition has on heat transfer. Multiple researchers have shown that superhydrophobic surfaces, those with a contact angle greater than 150° and contact angle hysteresis less than 5°, have demonstrated drag reduction for both laminar and turbulent flow on the order of 20% to 50% and slip lengths up to SO times larger than the feature length. This effort seeks to take a first step into understanding the effect that slip has on heat transfer. A 2-D parallel plate setup was evaluated. The velocity profile was analytically solved and used to determine the thermal profile using the Crank-Nicolson finite difference approach. The numerical results reveal that increasing the slip length improves heat transfer for a (h) 1.3 cm × (L) 15.2 cm parallel plate configuration. In addition, the temperature difference decays exponentially with Reynolds number, and a maximum temperature difference of 3.78 K between the no slip and 2 mm slip boundary conditions occurs at a Reynolds number of 90.
