Heat Transfer by Forced Convection from a Vertical PCM Plate
Authors: ,
Abstract: The article describes the possibility to obtain stored energy from PCM materials by using forced convection. The PCMs are very popular in many different applications for temperature stabilization of the microclimate inside buildings. The acceleration of releasing the stored energy is important for discharging cycle, which is very difficult to achieve because of the supercooling effect. Forced convection was used as an option for speeding-up the energy release. It is important to know some of the simple relations in fluid dynamics and boundary layer analysis to understand the forced convection heat transfer. Thermal imager was used for visualization of stored energy release. The paper also focuses on boundary layer with forced convection and the flow visualization around the surface of the vertical plate. It is possible to use the stored energy within several cycles. This energy can be used in various ways, such as a device with intermittent heating and cooling equipment. The aim is to develop a device which can be used for cooling or maintaining steady thermal conditions.
