Abstract

The numerical investigation of the flow and heat transfer of steady dusty flow over a linear stretching sheet has been carried out. The effects of Transverse force and electrification has been incorporated in this problem. Modelling of the problem comprises of highly nonlinear partial differential equations that have been transferred to systems of ordinary differential equations by implementing suitable transformations. Since the equations are of boundary value problems in nature, have been transferred to initial value problem by using shooting method and then solved by RungeKutta 4th order technique. All the above numerical methods incorporated in the BVP4C tool of MATLAB and has been solved the systems of differential equations by using MATLAB software. The effects of different parameter like Prandtl number, Eckert number, transverse force, and electrification parameter on flow and heat transfer profile has been presented through graphs and tables. The results have been validated with previous authors. From the graph it is observed that the transverse force reduces the velocity of the particle phase in the flow where as electrification of particles raises the temperature of particle phase in the flow. The computations carried out with tolerance of order less than O (10^(-6) ).

电气化和横向力对线性拉伸片上尘埃流的影响
对线性拉伸片上稳定尘埃流的流动和传热进行了数值研究。横向力和电气化的影响已被纳入该问题。该问题的建模包括高度非线性偏微分方程,通过适当的变换将其转换为常微分方程系统。由于这些方程在本质上属于边界值问题,因此采用射击法将其转换为初值问题,然后采用 RungeKutta 四阶技术进行求解。所有上述数值方法都已纳入 MATLAB 的 BVP4C 工具,并已通过 MATLAB 软件求解了微分方程系统。不同参数(如普朗特数、埃克特数、横向力和电气化参数)对流动和传热曲线的影响已通过图表呈现。研究结果与前人的研究结果进行了验证。从图中可以看出,横向力降低了流动中颗粒相的速度,而颗粒的电化则提高了流动中颗粒相的温度。计算公差小于 O (10^(-6) )。
