Comparative Analysis of Numerical Methods for Simulating N-Heptane Combustion with Steam Additive

Multi-Dimensional Simulation of n-Heptane Combustion under HCCI Engine Condition Using Detailed Chemical Kinetics

In this study, an in-house multi-dimensional code has been developed which simulates the combustion of n-heptane in a Homogeneous Charge Compression Ignition (HCCI) engine. It couples the flow field computations with detailed chemical kinetic scheme which involves the multi-reactions equations. A chemical kinetic scheme solver has been developed and coupled for solving the chemical reactions an...

On the combustion chemistry of n-heptane and n-butanol blends.

High-speed gas sampling experiments to measure the intermediate products formed during fuel decomposition remain challenging yet important experimental objectives. This article presents new speciation data on two important fuel reference compounds, n-heptane and n-butanol, at practical thermodynamic conditions of 700 K and 9 atm, for stoichiometric fuel-to-oxygen ratios and a dilution of 5.64 (...

Stability analysis of numerical methods for stochastic systems with additive noise

Stochastic differential equations (SDEs) represent physical phenomena dominated by stochastic processes. As for deterministic ordinary differential equations (ODEs), various numerical methods are proposed for SDEs. We have proposed two types of numerical stability for SDEs, namely mean-square stability and trajectory stability. However we have considered the analysis for the test equation with ...
