An analysis of the effect of orientation on the heat transfer in a scaled model pin fin heat sink utilized in Light Emitting Diode (LED) lighting has been carried out using numerical method. The present study involves natural convective heat transfer that takes place in particular heat sink. A pin fin type heat sink has been studied since they are widely used in LED lighting systems which in tu...

Stringent emission regulations around the world necessitate the use of high-efficiency catalytic converters in vehicle exhaust systems. Experimental studies are more expensive than computational studies. Also using computational techniques allows one to obtain all the required data for the Catalytic Converter, some of which could not be measured. In the present work, Geometric modeling ceramic ...

The aim of the present paper is to demonstrate how prosody information could be used to recognize Mandarin Chinese fluent speech and what the recognized results imply. By applying our hierarchical prosody framework for fluent speech [1, 2] that specifies boundary breaks and boundary information across phrases and group phrases into speech paragraphs, we were able to develop software that automa...

• Two numerical approaches (CPFD and TFM) are compared in a 3-D fluidized bed. Results of both models with pressure void fraction measurements. CPFD approach predicts lower frequencies the spectra. smaller bubbles velocities than TFM. is less sensitive to threshold value This paper presents results simulation freely bubbling bed, based on Eulerian–Lagrangian approach, using software Barracuda (...

The very first requirement to effectively use a computational fluid dynamics model is to prepare a 3D physical geometric model of the problem. Analysis of the fuel spray process involves specification of chamber space like bore and stroke of an internal combustion engine. Fluent software needs geometric meshing which in the present case is carried out using commercially available Gambit softwar...
