Abstract

A model is developed to predict the steady periodic performance of a radial flow desiccant wheel. The model is expressed in terms of the same dimensionless parameters that are commonly used in modeling of the conventional axial flow desiccant wheel. In addition a dimensionless geometrical ratio of the volume of the matrix to the volume of the wheel core is found to affect the performance of the wheel. A finite difference technique on staggered grid is used to discretize the governing dimensionless equations. The discretized equations are solved to predict the performance of the desiccant wheel at given values of operation parameters. A sensitivity study is carried out to investigate the effect of changing any of these parameters on the performance of the wheel. The performance of the radial flow desiccant wheel having the same values of the operation parameters.

Study of laminar, unsteady piston-cylinder flows

Journal Article Stroell, H; Durst, F; Peric, M; ... - Journal of Fluids Engineering

The present paper concerns numerical investigation of a piston-driven, axisymmetric flow in a pipe assembly containing a sudden expansion. The piston closes the larger of the two pipes. The impulsively starting intake flow is the topic of this investigation. Results of numerical calculations and laser-Doppler measurements are presented to provide an insight into the features of the flow. The calculation procedure employed in this study is based on a finite-volume method with staggered grids and SIMPLE algorithm for pressure-velocity coupling. The convection and diffusion fluxes in the Navier-Stokes equations are discretized with first order upwind and second order central differences,more »« less

Investigation on numerical method of one-dimensional drift flux model for boiling two-phase flow

Conference Hu, Lian; Chen, Deqi; Wang, Lin; ...

A numerical method for the solution of one-dimension drift-flux model has been developed. Correlations for heat and mass transfer and kinematic constitutive equation were used to close the set of the partial differential equations. The finite volume method based on the staggered grid and fully implicit backward Euler method were applied to discretize the spatial and time differential items, respectively. The discretization equations were solved iteratively in a same manner as in SIMPLE method for a single-phase flow. The verification and validation of the numerical method and closure model for one-dimension drift-flux model have been performed by comparing the codemore »« less
Numerical prediction of the buoyancy-driven flow in the annulus between horizontal eccentric elliptical cylinders

Journal Article Cheng, C; Chao, C - Numerical Heat Transfer. Part A, Applications

The present study is concerned with the buoyancy-driven airflow in an annulus between two asymmetrically heated horizontal eccentric elliptical cylinders. Flow patterns and heat transfer characteristics for various geometric configurations and heating conditions are predicted. The governing equations are discretized with the finite volume method on a curvilinear grid system generated numerically by the body-fitted coordinate transformation. Dependence of the equivalent conductivity on the physical and geometric parameters, such as the Rayleigh number, the dimensionless eccentricity, and the ratio of the areas of the cylinders, has been evaluated. results show that, for Ra > 10{sup 4}, the strength of themore »« less

Numerical analysis of flows of rarefied gases in long channels with octagonal cross section shapes

Journal Article Szalmas, L. - AIP Conference Proceedings

Isothermal, pressure driven rarefied gas flows through long channels with octagonal cross section shapes are analyzed computationally. The capillary is between inlet and outlet reservoirs. The cross section is constant along the axial direction. The boundary condition at the solid-gas interface is assumed to be diffuse reflection. Since the channel is long, the gaseous velocity is small compared to the average molecular speed. Consequently, a linearized description can be used. The flow is described by the linearized Bhatnagar-Gross-Krook kinetic model. The solution of the problem is divided into two stages. First, the local flow field is determined by assuming themore »« less

Convective heat transfer from a pulsating radial jet reattachment (PRJR) nozzle

Conference Pak, J; James, D; Parameswaran, S

Impinging jets of fluid have been used to cool, heat or dry surfaces in many industries including high temperature gas turbines, paper and glass manufacturing, textile drying, and electronic components. Jets may be broadly classified as either inline or radial. Inline jets typically have some type of circular or planer opening through which the fluid exits. The circular opening may be converging, well rounded, or of the same diameter as the nozzle or tube through which the fluid is delivered. Here, a numerical investigation for air exiting a Pulsating Radial Jet Reattachment (PRJR) nozzle was performed with various flow andmore »« less
