The current article investigates the effect of inclination angle on thermo-bioconvection within the porous-square shaped cavity filled with gyrotactic type microorganisms and nanofluid. The Darcy law with Boussinesq estimation is used for the momentum equation in porous media. The transformed governing equations are solved by Galerkin’s method of finite elements. The effect of inclination angle in the square cavity is interpreted by varying the angle from $\delta =0^0$ to $\delta ={180}^0$. The effect of inclination on different quantities, for instance, Rayleigh number, bioconvective Rayleigh number, Peclet number, Brownian motion, heat source/sink, and ratio of buoyancy, is discussed. Further, the mean quantities of Nusselt number $\left(N{u}_X\right)$, Sherwood number $\left(S{h}_X\right)$, and density number $\left(N{n}_X\right)$ are analyzed at vertical walls. A quantitative outcome of the study is that the maximum values of $N{u}_X$, $S{h}_X$, and $N{n}_X$ are found for the angle $\delta =\left({30}^0- {60}^0\right)$ and $\delta =\left({120}^0- {150}^0\right)$.

目前的文章研究了倾斜角对充满回旋型微生物和纳米流体的多孔方形腔内热生物对流的影响。具有 Boussinesq 估计的达西定律用于多孔介质中的动量方程。变换后的控制方程用伽辽金有限元法求解。方腔中倾角的影响是通过改变角度来解释的$\delta =0^0$ 到 $\delta ={180}^0$. 讨论了倾角对不同量的影响，例如瑞利数、生物对流瑞利数、Peclet 数、布朗运动、热源/汇和浮力比。此外，努塞尔数的平均数量$\left(N{你}_X\right)$, 舍伍德数 $\left(秒H_X\right)$, 和密度数 $\left(N{n}_X\right)$在垂直墙壁上进行分析。研究的定量结果是最大值$N{你}_X$, $秒H_X$， 和 $N{n}_X$ 找到角度 $\delta =\left({30}^0- {60}^0\right)$ 和 $\delta =\left({120}^0- {150}^0\right)$.
