Simulation of Free Convection from an Inclined Heated Thin Plate in a Square Enclosure

Simulation of free convection heat transfer in a square enclosure induced by heated thin plate is represented numerically. All the enclosure walls have constant temperature lower than the plate’s temperature. The flow is assumed to be two-dimensional. The discretized equations were solved stream f...
