Objective
The liquid which is driven back to the evaporated meniscus has to be re-supplied to maintain the operation of CPHTD. When evaporation exceeds the rate of liquid re-supply, the device is said to reach its capillary limit and fails. Therefore, it is necessary to investigate how flow and temperature fields are established and developed in a capillary pore as a combined result of buoyancy, thermocapillarity, and interfacial evaporation. The objective is to study these three effects on the flow and temperature field development inside a capillary pore region near the evaporating meniscus
