The aim of this study is to discover the characteristics of the cooling water in the cylinder head of a high-power diesel engine by using the Computational Fluid Dynamics (CFD). A 3-D geometric model of a cylinder head water jacket was previously constructed using Unigraphics software. A mesh was then imposed on the model using the preprocessor of Fluent software, GAMBIT. Three types of thermal...

The tall building is the most dominating symbol of the cities and a human made marvel that defies gravity by reaching to clouds. The development of high strength concrete, higher grade steel, new construction techniques and advanced computational technique has resulted in the emergence of a new generation of tall structures that are flexible, low in damping, slender and light in weight. These t...

We compare click production in fluent speech to previously analyzed clear productions in the Namibian Kx’a language Mangetti Dune !Xung. Using a rule-based software system, we extract clicks from recorded folktales, with click detection accuracy about 65% f-score for one storyteller, reducing manual annotation time by two thirds; we believe similar methods will be effective for other loud, shor...

This paper uses CFD software ANSYS Fluent, based on RSM Reynolds stress model and VOF two-phase flow model, to calculate the turbulent field inside ∅75mm heavy dispersed phase particle separation cyclone. Combined with experimental working parameters under different inlet pressures, results were compared. Check accuracy of formula calculation numerical simulation results. The show that air colu...

Kurzfassung. Patientenspezifische Strömungsund die Geometrieanalyse von Aneurysmen basiert auf der 3D-Rekonstruktion aus Daten, die mit modernen Methoden der Bildgebung (z.B. CT und MRT) gewonnen werden. Die unterschiedlichen Charakteristika der Bildgebungsverfahren und die damit verbundenen Unsicherheiten führen zu Variationen der rekonstruierten Geometrien, die sich auf die numerische Berechn...

A new cooling duct system was developed in order to increase the refrigerator performance in terms of uniform temperature distribution particle image velocimetry (PIV) and the commercial software FLUENT was used to compare the performance of the conventional cooling system with the new cooling system. The new cooling system effectively cooled the door basket region, thus increasing the uniformi...

Regulations and customer demands put pressure on rail designers to deliver passenger coaches with comfortable climates. In the past, Siemens engineers spent about four months testing passenger coaches in a climate wind tunnel to validate the design of the heating, ventilation and cooling (HVAC) system. Now they use ANSYS Fluent computational fluid dynamics (CFD) software to validate the design ...

A penalization method is applied to model the interaction of large Mach number compressible flows with obstacles. A supplementary term is added to the compressible Navier-Stokes system, seeking to simulate the effect of the Brinkmanpenalization technique used in incompressible flow simulations including obstacles. We present a computational study comparing numerical results obtained with this m...
