Revisit of Diesel Reference Fuel (n-Heptane) Mechanism Applied to Multidimensional Diesel Ignition and Combustion Simulations

ABSTRACT Two reduced n-heptane mechanisms, previously developed in 1998 (40 species and 165 reactions) and in 2000 (65 species and 273 reactions) respectively, were revisited and the mechanism improvement was pursued. In the newly revised version, the mechanism consists of 83 species and 445 reactions. The mechanism was validated against the auto-ignition delay times of n-heptane/air mixture me...

A Novel Assisted History Matching Workflow and its Application in a Full Field Reservoir Simulation Model

The significant increase in using reservoir simulation models poses significant challenges in the design and calibration of models. Moreover, conventional model calibration, history matching, is usually performed using a trial and error process of adjusting model parameters until a satisfactory match is obtained. In addition, history matching is an inverse problem, and hence it may have non-uni...

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...

Stoichiometric Combustion Model with Oxygen Threshold Improved Predictions for Fire Simulation Using a CFD Model

This paper examines the effect of various combustion models when predicting the environment in a building arising from fire in a room. The use of a stoichiometric combustion model will usually over-predict the efficiency of the combustion process in the fuel-rich areas and hence over-predict the temperature field. A modified combustion model presented in this paper can improve the predicted res...
