CFD model fluid drag loss distribution for the deep groove ball bearing (top) and radial needle roller bearing (bottom). To further investigate the sources of fluid drag losses in the CFD simulations, bearing cage wall shear stress and fluid velocity were plotted for the highest and lowest Reynolds number operating conditions.

In this study, we investigate a computational fluid dynamics (CFD) model that accounts for these effects and verify it experimentally for a range of roller speeds and polymer concentrations. The presented study should also answer the question if a 2 …

Instead of individual air flaps in the grill, the Active Air Blinds use a textile blind in the front of the vehicle. The system works like a roller blind: when the textile is rolled up, it opens the way into the engine compartment. To close, the integrated cable guide pulls the blind in front of the air inlets. This works infinitely variable.

The meshing process is a significant step in CFD modelling and requires considerable attention. In order to analyse the fluid flow, the domain must be subdivided into smaller cells. Essentially, the accuracy of a CFD solution depends upon the number of cells in the mesh. The finer mesh, the better precision of the solution [38].

The current work presents a CFD model capable of modelling heat and mass transfer processes across a membrane heat exchanger of variable mass transportation resistance using FLUENT. A user define function (UDF) has been developed and incorporated into FLUENT to model the variation in the transportation resistance of the membrane heat exchanger.

complex variable math (such as 18.075). Bernoulli Equation The Bernoulli equation is the most widely used equation in fluid mechanics, and assumes frictionless flow with no work or heat transfer. However, flow may or may not be irrotational. When flow is irrotational it reduces nicely using the potential function in place of the velocity vector.

The effect of roller structural parameters on polishing flow field pressure during linear hydrodynamic polishing (LHP) was optimized by applying orthogonal test design. We used CFD simulation results to analyze the effect of structural parameters on the magnitude and uniformity of hydrodynamic pressure. By using the nlinfit fitting method, multiple nonlinear regression equations for …

The variable-structure boat is mainly composed of mainhull (planing hull), twin side-hulls and outrigger. Its mainhull is slender, square-tailed, non-stepped, has a larger knuckle line width, and a plurality of spray deflectors with variant dimensions are symmetrically installed at its hull bottom to improve its seakeeping and resistance performance.
