The present work examines heat and mass transfer characteristics of peristaltic motion of Johnson-Segalman fluid in a tapered asymmetric channel along with chemical reaction, by taking into account the Soret and Dufour effects. Effects of Hall current have also been discussed in mathematical modeling and analysis. Following the peristaltic wave procedure, the tapered asymmetric channel is based on the non uniform boundaries having diverse phases and amplitudes. The channel walls show excellent agreement with more realistic convective conditions. The modeled flow problem is directed into ordinary differential equations set with proper utilization of similarity quantities. The estimation of high wavelength as well as small Reynolds number are acknowledged to deduce the equations of Johnson-Segalman liquid model. The adopted solution procedure is constructed via homotopic algorithm. The results have been analyzed for various parameters of interest and sketched for better understand...

Soret和Dufour在存在霍尔电流的情况下在锥形不对称通道中化学反应性流体的蠕动特征

本工作通过考虑Soret和Dufour效应，研究了锥形不对称通道中Johnson-Segalman流体蠕动运动的传热和传质特性以及化学反应。在数学建模和分析中还讨论了霍尔电流的影响。遵循蠕动波程序，锥形不对称通道基于具有不同相位和幅度的非均匀边界。通道壁与更现实的对流条件显示出极好的一致性。通过适当利用相似性量，将建模的流动问题引入到常微分方程组中。公认的是对高波长的估计以及较小的雷诺数，以推导Johnson-Segalman液体模型的方程。通过同位算法构造所采用的求解过程。对结果进行了分析，分析了各种令人感兴趣的参数，并草绘以更好地理解...
