The incompressible two-dimensional steady flow of Sutterby fluid over a stretching cylinder is taken into account. The magnetic Reynolds number is not deliberated low in the present analysis. Radiation and variable thermal conductivity are considered to debate the impact on the cylindrical surface. The Dufour and Soret impacts are considered on the cylinder. The mathematical model is settled by employing boundary layer approximations in the form of differential equations. The system of differential equations becomes dimensionless using suitable transformations. The dimensionless nonlinear differential equations are solved through a numerical scheme(bvp4c technique). The flow parameters of physical effects on the velocity, temperature, heat transfer rate, and friction between surface and liquid are presented in tabular as well as graphical form. The velocity function declined by improving the values of the Sponginess parameter. The fluid temperature is reduced by increment in curvature parameter.
考虑了Sutterby流体在拉伸圆柱上的不可压缩二维稳态流动。在本分析中，磁雷诺数不被视为小量。考虑辐射和可变热导率以讨论对圆柱表面的影响。考虑了圆柱上的杜福尔和索雷特效应。通过采用边界层近似形式的微分方程建立数学模型。利用适当的变换使微分方程组无量纲化。通过数值方案（bvp4c技术）求解无量纲非线性微分方程。以表格和图形形式给出了物理效应的流动参数对速度、温度、传热速率以及表面与液体之间摩擦力的影响。速度函数随着海绵状参数值的增加而下降。流体温度随着曲率参数的增加而降低。
