Environmental particle rebound/deposition modeling in engine hot sections

Procedural audio modeling for particle-based environmental effects

We present a sound synthesizer dedicated to particle-based environmental effects, for use in interactive virtual environments. The synthesis engine is based on five physically-inspired basic elements which we call sound atoms, that can be parameterized and stochastically distributed in time and space. Based on this set of atomic elements, models are presented for reproducing several environment...

A hot air driven thermoacoustic-Stirling engine

Engine Modeling of an Internal Combustion Engine

In the modern world, one of the largest concerns is the ever depleting supply of oil. The automotive industry is especially impacted. In recent years the price of gasoline has fluctuated substantially and the price of crude oil has reached record highs. The high price of gasoline coupled with the uncertainty of its availability and future price have put a high priority on fuel economy of an eng...

Soot Modeling in Diesel Engine

This paper presents an advanced version of the original software developed by the author in order to simulate the combustion in the Diesel engines, focusing on simulate soot formation. Complex kinetic mechanisms are need for realistic modeling of shoot formations, but this is applicable only for simple flame computations (e.g. one dimensional, laminar, etc.). For real turbulent flame calculatio...

Radiation modeling of a turbulent diffusion flame in diesel engine

The purpose of this study is to investigate the effect of radiation heat transfer on temperature distribution and heat flux to the walls of a diesel engine. A diffusion flame is modeled in a simple cylindrical geometry and boundary conditions are defined. A specific solver which can model the turbulent diffusion flame by considering radiation in participating media is used to solve the problem....
