The purpose and novelty of our study include the scrutinization of the unsteady flow and heat characteristics of the unsteady Sutterby nano-fluid flow across an elongated cone using slip boundary conditions. The bioconvection of gyrotactic micro-organisms, Cattaneo-Christov, and thermal radiative fluxes with magnetic fields are significant physical aspects of the study. Anisotropic constraints on the cone surface are taken into account. The leading formulation is transmuted into ordinary differential formate via similarity functions. Five coupled equations with nonlinear terms are resolved numerically through the utilization of a MATLAB code for the Runge-Kutta procedure. The parameters of buoyancy ratio, the porosity of medium, and bioconvection Rayleigh number decrease x-direction velocity. The slip parameter retard y-direction velocity. The temperature for Sutterby fluids is at a hotter level, but its velocity is vividly slower compared to those of nanofluids. The temperature profile improves directly with thermophoresis, v-velocity slip, and random motion of nanoentities.
我们研究的目的和新颖之处包括使用滑移边界条件，仔细研究不稳定的萨特比纳米流体流过细长圆锥体时的非定常流动和热特性。趋旋微生物的生物对流、卡塔尼奥 - 克里斯托夫以及磁场作用下的热辐射通量是该研究的重要物理方面。考虑了圆锥表面的各向异性约束。通过相似函数将主导公式转化为常微分形式。利用MATLAB代码通过龙格 - 库塔过程对五个带有非线性项的耦合方程进行数值求解。浮力比参数、介质孔隙率和生物对流瑞利数会降低x方向速度。滑移参数会阻碍y方向速度。萨特比流体的温度处于较高水平，但其速度与纳米流体相比明显较慢。温度分布直接随着热泳、v - 速度滑移和纳米实体的随机运动而改善。
