Axi-symmetric Stagnation–Point Flow and Heat Transfer Obliquely Impinging on a Rotating Circular Cylinder
Laminar stagnation flow, axi-symmetrically yet obliquely impinging on a rotating circular cylinder, as well as its heat transfer is formulated as an exact solution of the Navier-Stokes equations. Rotational velocity of the cylinder is time-dependent while the surface transpiration is uniform and steady. The impinging stream is composed of a rotational axial flow superposed onto irrotational rad...
متن کاملCFD-Calculation of Fluid Flow in a
An accurate description of the fluid flow and heat transfer within a Pressurized Water Reactor (PWR), for the safety analysis and reactor performance is always desirable. In this paper a mathematical model of the fundamental physical phenomena which are associated to a typical PWR is presented. The mathematical model governs the fluid dynamics in the reactor. Using commercial software CFX, a co...
متن کاملNumerical Calculation of the Flow in a Centrifugal Pump Impeller Using Cartesian Grid
The simulation of the three-dimensional turbulent flow in turbomachines is currently based on the solution of the Reynolds Averaged Navier Stokes equations. A considerable computational effort usually goes to the mesh generation process due to the complexity of the impeller geometry. The use of Cartesian grids combined with a numerical technique for solving partially blocked cells is presented ...
متن کاملSimulation of axi-symmetric flow towards wells: A finite-difference approach
A detailed finite-difference approach is presented for the simulation of transient radial flow in multi-layer systems. The proposed discretization scheme simulates drawdown within the well more accurately than commonly applied schemes. The solution is compared to existing (semi) analytical models for the simulation of slug tests and pumping tests with constant discharge in singleand multi-layer...
متن کاملAnalytical Modeling of Axi-Symmetric Sheet Metal Forming
The cup drawing is a basic deep drawing process. Thus, understanding the mechanics ofthe cup drawing process helps in determining the general parameters that affect the deep drawingprocess. There are mainly two methods of analysis; experimental and analytical/numerical.Experimental analysis can be useful in analyzing the process to determine the process parameters thatproduce a defect free prod...
