This research communicates the thermal assessment of Sutterby nanofluid containing the gyrotactic microorganisms with solutal and Marangoni boundaries. The applications of melting phenomenon and thermal conductivity are also considered. The flow is confined by a stretched cylinder. The prospective of Brownian motion and thermophoresis diffusions are also taken account via Buongiorno nanofluid model. The problem is formulated with help of governing relations and equations which are altered into dimensionless form via appropriate variables. The numerical scheme based on shooting scheme is employed to access the solution. A comparative analysis is performed to verify the approximated solution. The observations reveal that the velocity profile enhanced with the Marangoni number while a declining velocity profile has been observed with Sutterby nanofluid parameter and Darcy resistance parameter. The nanofluid temperature get rise with thermal conductivity parameter and thermal Biot number. An arising profile of nanofluid concentration is observed for concentration conductivity parameter and buoyancy ratio parameter.

这项研究传达了包含具有溶质边界和Marangoni边界的旋回微生物的Sutterby纳米流体的热评估。还考虑了熔化现象和热导率的应用。流动受拉伸圆柱体的限制。通过Buongiorno纳米流体模型还考虑了预期的布朗运动和热泳扩散。通过控制关系和方程式来解决该问题，这些关系式和方程式通过适当的变量变为无量纲形式。采用基于射击方案的数值方案来求解。进行比较分析以验证近似解。观测结果表明，速度分布随Marangoni数增加，而Sutterby纳米流体参数和达西阻力参数则观察到速度分布下降。纳米流体的温度随着导热系数和热比奥数的增加而升高。对于浓度电导率参数和浮力比参数，观察到纳米流体浓度的上升曲线。
