Due to practical applications, convective heat transfer in a square chamber has been an important subject numerically. Also, the management of Heat Transfer Conductance Coefficients (HTCCs) in an enclosing wall has a remarkable influence. Based on handling of regions close to wall, the equation for convective heat transfer coefficient is acquired. Meanwhile, the dimensionless local Nu number is also obtained as well as average Nu number. For the enclosure with convective heat transfer, to affirm the applied model, the influence of first grid point position is analyzed and the position of the first grid point is suggested to be less than 0.5mm.
