不可压缩Navier-Stokes方程组是一个非常重要的刻画黏性流体运动的物理模型,迄今已有将近200年的历史.对Navier-Stokes方程的真正的数学理论研究是从20世纪30年代法国数学家Leray[3]关于弱解的整体存在性的奠基性工作开始的.后来,德国数学家Hopf[4]...

In this study, we examine the nature of magnetohydrodynamic (MHD) Casson flow of fluid across a stretched surface in a porous material. It studies how the behaviour of Casson fluids is affected by a number of variables, including thermal radiation, chemical processes, Joule heating, and ...
Aims.The driver of the SSI variability is understood to be the intensity contrast of magnetic features present on the Sun with respect to the largely non-magnetic quiet Sun. However, different spectral synthesis codes lead to diverging projections of SSI variability. In this study we compare three...
A numerical study that considers the complete electric flow coupling in the blanket for assumed fully developed conditions in a middle cross-section of the module, demonstrates the strong interaction of subchannels in one BU, whereas only a weak coupling is found between neighboring BUs [4]. To...
Nevertheless, the amplitude of the m/n = 4/2 mode is much smaller than that of the m/n = 2/1 mode. In this study, the safety factor (q) is estimated as follows: (i) before the TQ onset, the q profile is calculated by the E FIT42 reconstruction, which is internally ...

In the present study, the MHD mixed convection flow over a permeable vertical flat plate embedded in a Darcy–Brinkman porous medium has been performed using both analytical and numerical solutions. Double (upper and lower branch) solutions, with respect to the involved parameters: G (non-Darcy ...
This study examines the impact of cross-diffusion, internal heat sources, chemical reactions, and magnetohydrodynamics on the boundary layer flow of a nanofluid within a saturated porous medium subjected to an exponentially stretching sheet. The system of partial differential equations (PDEs) governing ...
