摘要
In this work, the role of various configurations of wavy circular heater and nanoparticles on convective heat transfer inside an enclosure having a wavy circular heater is explored. Various configurations of the inner wavy heater are considered. Numerical solutions of dimensionless governing equations are obtained via a hybrid method called Control Volume Finite Element Method (CVFEM). The influence of active parameters e.g. undulation number, wavy contraction ratio and so on is perused on convective heat transfer. According to the outcomes, it was found that the configuration of the wavy heater plays a crucial role in controlling the convective flow characteristic and the heat transfer rate within the enclosure. Hence, the present study can be a useful source for the manufactures of heated elements.
