With the spread of sustainability concepts, due to global energy crisis and unrestrained consumption natural resources, importance rational use reduction has been intensified, albeit in short steps. This concern taken up bioclimatic concepts buildings, especially housing buildings for low-income people, aiming at improving quality production terms its habitability. The objective this research i...

A pressure-based computational fluid dynamics (CFD) code is employed to calculate the flow field and rotordynamic forces in a whirling, grooved liquid annular seal. To validate the capabilities of the CFD code for this class of problems, comparisons of basic fluid dynamic parameters are made to three-dimensional laser Doppler anemometer (LDA) measurements for a spinning, centered grooved seal. ...

An operating 2-MW wind turbine has been scanned and analysed using 2D computational fluid dynamics (CFD) blade element momentum (BEM) analysis. The current work illustrates full-scale 3D CFD simulations the differences between its impact on local aerofoil vortex shedding frequency. outcome shows that despite a pressure redistribution lift change introduced by span rotation, frequency remains si...

An integrated computational  uid dynamics (CFD) and computational structural dynamics (CSD) method is developed for the simulation and prediction of  utter. The CFD solver is based on an unsteady, parallel, multiblock, multigrid Ž nite volume algorithm for the Euler/Navier–Stokes equations. The CSD solver is based on the time integration of modal dynamic equations extracted from full Ž nite e...

This comparative cross-sectional study was conducted in the pediatric daycare unit, Hospital Universiti Sains Malaysia to determine the prevalence of craniofacial deformities (CFD) and the association between these deformities and different clinical presentations among thalassemia patients. Patients were classified as either craniofacial deformity positive (CFD+) or craniofacial deformity negat...

in today's design, system complexity and increasing demand for safer, more efficient and less costly systems have created new challenges in science and engineering. locomotives are products which are designed according to market order and technical needs of customers. accordingly, targets of companies, especially designers and manufacturers of locomotives, have always been on the path of progre...

wide range of planar structures in new technologies has attracted special consideration. in this research vibration behavior of plates with non-linear edges is investigated by means of finite difference (fd) method. for this issue, classical and analytical solutions for plates with linear edges were analyzed and mutual equations, needed for numerical calculation were extracted. by expanding the...
