A computer model of heat transmission in a square cavity was created in order to have a better understanding of the consequences. Temperature differences between the top and bottom walls are what cause convection, whereas the remaining left and right walls remain adiabatic and do not contribute to the process (unheated). In order to provide an accurate estimate of the two-dimensional steady flow inside a square cavity, a novel finite volume (FV) method that incorporates adaptive upwind convection is applied. Due to natural convection’s widespread use in the industrial sector, a significant amount of research has been conducted on the topic of how its usage affects the rate of heat transfer in enclosed areas. In a square cavity, the equations for the mass balance, momentum balance, and energy balance of the system are studied.

为了更好地了解结果，我们创建了方形空腔中热传输的计算机模型。顶壁和底壁之间的温差是导致对流的原因，而其余的左壁和右壁保持绝热并且对过程没有贡献（未加热）。为了准确估计方形空腔内的二维稳态流动，应用了一种结合自适应逆风对流的新型有限体积 (FV) 方法。由于自然对流在工业领域的广泛应用，人们对其使用如何影响封闭区域的传热速率这一主题进行了大量研究。在方形空腔中，研究了系统的质量平衡、动量平衡和能量平衡方程。
