توسعه یک روش عددی حجم محدود برای ارزیابی عملکرد هیدرودینامیکی سازه های دریایی
Development of a compatible computational fluid dynamics procedure to investigate rigid and fixed/free coastal and offshore structures hydrodynamics in a time-dependent one/two phase flow of viscous incompressible fluids is presented. Differential governing equations are discretised using finite volume approach based on a colocated arrangement. The conservation equations for mass and momentum a...
متن کاملNumerical study of heat transfer in fluidized bed dryers by volume of fluid method
The purpose of this study is numerical modeling of temperature variation of phases in a two phase regime in fluidized bed dryers including particles belonging to Group D of geldart classification. The mass transfer between phases is not taken into consideration in this modeling which has been assumed in three- dimensional, unsteady, and two-phase regime.To verify the modeling we consider the do...
متن کاملDevelopment of a phase change model for volume-of-fluid method in OpenFOAM
In this present study, volume of fluid method in OpenFOAM open source CFD package will be extended to consider phase change phenomena with modified model due to condensation and boiling processes. This model is suitable for the case in which both unsaturated phase and saturated phase are present and for beginning boiling and condensation process needn't initial interface. Both phases (liquid-va...
متن کاملA NUMERICAL STUDY OF SINGLE-PHASE FORCED CONVECTIVE HEAT TRANSFER WITH FLOW FRICTION IN MICROCHANNELS (RESEARCH NOTE)
Three-dimensional simulations of the single-phase laminar flow and forced convective heat transfer of water in microchannels with small rectangular sections having specific hydraulic diameters and distinct geometric configurations were investigated numerically. The numerical results indicated that the laminar heat transfer was to be dependent upon the aspect ratio and the ratio of the hydraulic...
متن کاملApplication of the Schwarz-Christoffel Transformation in Solving Two-Dimensional Turbulent Flows in Complex Geometries
In this paper, two-dimensional turbulent flows in different and complex geometries are simulated by using an accurate grid generation method. In order to analyze the fluid flow, numerical solution of the continuity and Navier-Stokes equations are solved using CFD techniques. Considering the complexity of the physical geometry, conformal mapping is used to generate an orthogonal grid by means of...
