Abstract The phenomena of buoyant Marangoni natural convection in a right-angled trapezoidal enclosure filled with water-based nanofluids have been studied numerically. The left vertical wall of the trapezoidal cavity is heated uniformly, the right inclined wall is cooled, and the top and bottom walls are insulated (adiabatic). The finite element method (FEM) is implemented to solve the non-dimensional governing equations. The investigation has been done for different values of parameters: the aspect ratio of the enclosure, Ar the nanoparticles volume fraction, the Marangoni numbers, Ma bf and the Rayleigh numbers, Ra bf

直角梯形腔中纳米流体的浮力 Marangoni 对流

摘要 数值研究了在充满水基纳米流体的直角梯形外壳中的浮力 Marangoni 自然对流现象。梯形腔体左侧垂直壁受热均匀，右侧斜壁冷却，上下壁隔热（绝热）。实施有限元方法 (FEM) 来求解无量纲控制方程。已针对不同的参数值进行了调查：外壳的纵横比、Ar 纳米颗粒体积分数、Marangoni 数、Ma bf 和瑞利数、Ra bf
