MHD viscoelastic (Walters’-B) fluid flow close to the stagnation point region along an extending plate with the changeable fluid properties’ influences has been debated. Heat transfer’s features are scrutinized via Cattaneo–Christov (CC) theory. The mathematical model for the physical problem is tackled numerically via Chebyshev pseudospectral (CPS) technique. The existing outcomes are supported by recent research and have acquired a suitable agreement. The numerical outcomes reveal that temperature fields are more pronounced for Fourier’s law case. Further, the opposite behavior is noticed with the heat transfer rate. Higher values of the conjugate parameter result in an increment of the heat transfer rate and temperature field. Fluid flow’s features, as well as physical quantities, are substantially varied via variable fluid properties.

牛顿加热、可变流体特性和 Cattaneo-Christov 模型对拉伸表面诱导的 Walters B 流体 MHD 驻点流动的影响

MHD 粘弹性 (Walters'-B) 流体沿延伸板靠近驻点区域流动，具有可变流体特性的影响一直存在争议。通过 Cattaneo-Christov (CC) 理论仔细研究了传热的特征。物理问题的数学模型通过切比雪夫伪光谱 (CPS) 技术进行数值处理。现有结果得到了最近研究的支持，并已获得合适的协议。数值结果表明，对于傅立叶定律，温度场更为明显。此外，通过传热速率注意到相反的行为。较高的共轭参数值导致传热速率和温度场的增加。流体流动的特征以及物理量通过可变的流体特性而发生很大变化。
