one of the main architectural characteristics in the central area of iran is the relation between life and climatic conditions; e.g., the four-seasonal house which is a typical kind of the central-yard house. as the climate of isfahan is more pleasant than other desert regions in the central part of iran, wind towers are replaced with skylights to ventilate the pool area of hoze-khane. so far, ...

the purpose of this study is to identify parameters influence on the particle deposition within fin and tube heat exchanger of air-conditioning systems by cfd analysis. first the basic sketch of periodic geometry drawn and meshing operation including boundary conditions was performed. then the gas side properties and flow parameters were solved by ansys fluent 14.5 software. lagrangian equation...

Abstract Thrust eccentricity refers to the phenomenon that thrust vector deviates from axis of symmetry. This will produce lateral force and torque around aircraft, which affects normal flight increases required control torque, reduces density uncontrolled rockets. There are three sources eccentricity: mass eccentricity, geometric aerodynamic eccentricity. The is caused by asymmetrical flow com...

in this research, the numerical method of computational fluid dynamics and dimensionless parameter of froude number have been applied to determine the flow regime over ogee spillways.froude number is a dimensionless dynamic parameter calculated using the square root of the ratio of inertia force and gravitational force. considering that the study of the regimes of flow over hydraulic structures...

A study to further simulation research of a commercial chemical vapor deposition (CVD) reactor is presented. A simulation is created using the computational fluid dynamics software package, Fluent (version 4). The variation of gas temperature inside the reactor system, as a function of gas flow rate, is examined. Data is collected for trials of several initial flow rates and iterations. Results...

Recently, version 3.0a of the software package FEMLAB for solving multiphysics partial differential equations was released. In the present project we compared its performance with the previous release 2.3 and the package Fluent 6.1 in stationary laminar flow benchmark problems in two and three dimensions. It turns out that the new version is an essential improvement over the old version. It is ...
