Convective energy transport can be found in various engineering and nature systems. From practical point of view this transport phenomenon within engineering cabinets can be progressed in the presence of temperature modulation. In this research, the transient natural convective heat transference of a temperature-dependent viscosity liquid inside an inclined cube in the presence of time-dependent temperature profile at one vertical bounded surface is investigated. The opposite vertical border is kept at permanent low temperature, whilst other surfaces are thermally insulated. Partial differential equations formulated using dimensionless non-primitive characteristics with appropriate restrictions are worked out by the finite difference technique. Impacts of the domain tilted angle, and wall temperature oscillation frequency on energy transport and flow structures are scrutinized.

对流能量传输可以在各种工程和自然系统中找到。从实际的角度来看，在存在温度调节的情况下，工程柜内的这种运输现象可以发展。在这项研究中，研究了在一个垂直边界表面上存在时间相关温度曲线的情况下，倾斜立方体内部温度相关粘度液体的瞬态自然对流传热。相对的垂直边界保持在永久低温下，而其他表面则被隔热。通过有限差分技术，计算出了使用无量纲非本原特征并有适当限制的偏微分方程。畴倾斜角的影响
