This investigation aims to study Magnetohydrodynamics (MHD)two-dimensional incompressible boundary layer performing non-Newtonian Carreau ternary-hybrid nanofluid flow with heat transfer through an exponential stretching curved surface. The has been synthesized titanium oxide, aluminum and silver dispersionin the base fluid water. TheNavier Stokes equation model govern partial differential equa...
MHD boundary layer flow of two phase model nanofluid over a vertical plate is investigated both analytically and numerically. A system of governing nonlinear partial differential equations is converted into a set of nonlinear ordinary differential equations by suitable similarity transformations and then solved analytically using homotopy analysis method and numerically by the fourth order Rung...
Bottom boundary layer effects on the linear wave propagation over mild slope bottoms are analyzed. A modifiedWKB approximation is presented including boundary layer effects. Within the boundary layer, two cases are considered: laminar (constant viscosity) and turbulent. Boundary layer effects are introduced by coupling the velocity inside the boundary layer to the irrotational velocity in the c...
An algorithm suitable for numerical solution of linear eigenmode problems in resistive magnetohydrodynamics MHD and two-fluid MHD models without prior approximations is presented. For these plasma models, sets of equations suitable for numerical solution are derived and the details of the algorithm of this solution are given. The algorithm is general and is suitable for solution of boundary eig...
چکیده: آنچه که در این تحقیق به آن پرداخته خواهد شد ، حل معادلاتِ دینامیکِ سیالات هادی جریان الکتریکی(mhd equation) برروی استوانه ای از جنس غشای نفوذپذیر، در حضور میدان مغناطیسی همراه با انتقال جرم می باشد.پس معادلات انتقال جرم و (mhd) را در مختصات استوانه ای استخراج کرده و حل تشابهی برای آنها انجام می دهیم. برای استخراج و حل معادلات مذکور فیزیک مساله را درنظر می گیریم ، که استوانه ای است از جنس ...
Confining dense plasma in a field reversed configuration (FRC) is considered a promising approach to fusion. Numerical simulation of this process requires setting artificial boundary conditions (ABCs) for the magnetic field because whereas the plasma itself occupies a bounded region (within the FRC coils), the field extends from this region all the way to infinity. If the plasma is modeled usin...
This paper presents a theoretical study on the velocity distribution and the friction factor of boundary layer flows with polymer additives starting from the concept of “stress deficit.” A novel method of order of magnitude analysis is developed, which converts the governing equations of boundary layer flow into a solvable ordinary differential equation, thus the total shear stress distribution...
In the paper, we establish existence of steady boundary layer solution Boltzmann equation with specular condition in L 2 ∩L ∞ half-space. The uniqueness, continuity and exponential decay are obtained, such estimates important to prove Hilbert expansion for half-space problem condition.
Magnetic reconnection is of great interest in many space and laboratory plasmas [1,2], and has been studied extensively for more than four decades. The most important question is that of the reconnection rate. The process of magnetic reconnection, is so complex, however, that this question is still not completely resolved, even within the simplest possible canonical model: twodimensional (2D) i...
Recent developments in the field of fluid dynamics have led to a new interest stability analysis. The numerical solution obtained from problems flow at stagnation point, as well heat transfer with MHD and thermal radiation effects over shrinking sheet, is used carry out this problem considered nanofluids Buongiorno's model employed. boundary layer equation by reducing governing equations an ord...
