Week 7 - Auto ignition using Cantera

1. Objective : To carry out Sensitivity Analysis of GRI 3.0 Mechanism for finding out the Top 10 Reactions, upon which the Final System Temperature depend the most.   Introduction : Sensitivity, in context of Chemical Kinetics is referred to as the dependence of an Output Variable (like Temperature), on an Input Parameter…

1. Objective : To understand the variation of Ignition Delay with change of Initial Temparature & Pressure. To depict the variation of Mole Fraction of several species with different Initial Temparatures. Introduction : We shall consider the Stoichiometric Combustion of Methane, the Chemical Reaction for which, is…

1.  An Ordinary ifferential Equation is an equation containing one or more functions of one independent variable and the derivatives of those functions. Solving them are of paramount importance, as they govern a range of phenomena. One of the key characteristics of the Solution to an Ordinary Diefferntial Equation…

1. Objective : To observe the effect of Pre-Heating the Inlet Air on parameters like Adiabatic Flame Temparature, Combustion Efficiency & Fuel Consumption. Introduction : We consider here a Furnace, inside which, Constant Pressure Stoichiometric Combustion of Methane is taking place. We use a Recuperator (which is…

1.  Objective : To calculate the Adiabatic Flame Temparature of Stoichiometric Combustion of Methane by specifying Fuel & Oxidizer as separate Mixtures, using the Quantity Class in Cantera. Introduction :  General form of Stoichiometric Hydro-Carbon Combustion Reaction with a single Fuel Species : CxHyOz…

1.  Objective :   Our primary objective here is to compare results between Python & Cantera for the following cases : Variation of AFT with Equivalence Ratio (during a Constant Volume Process) Variation of AFT with Heat Loss Factor (during a Constant Pressure Process) Variation of AFT with Number of Bonds…

PROJECT 1 : Adding Passive Scalar Transport Equation to icoFoam (icoFoam -> scalarFOAM)   Introduction :  icoFoam is a transient solver for incompressible & laminar flows. It solves the Navier-Stoke's equation using the PISO (Pressure Implicit with Splitting of Operators) algorithm. The need of Pressure-Velocity…
