Development of adaptive kinetics for application in combustion systems

Biodiesel, emulsified biodiesel and dimethyl ether as pilot fuels for natural gas fuelled engines

“…For example, there is significant attention placed on producing a new generation of energyconversion powerplants. The main focus has been on improving the three key parameters of powerplant performance; thermal efficiency, specific power and emissions [2][3][4][5]. While the basic measure of performance is thermal efficiency, there is an increasing need to extract more power from smaller powerplants [4,[6][7][8].…”

Automatic generation of skeletal mechanisms for ignition combustion based on level of importance analysis

“…(3) the LOI may need to be multiplied by the species' concentration to obtain a non-dimensional sensitivity parameter [21,22]. Furthermore, it is possible to include the sensitivity towards variables such as temperature or flame speed, and even a multiple of sensitivity targets where the maximum value towards the selected targets is employed in the computation of the LOI index.…”

“…This work included also a detailed investigation of the coupling between the LOI and the steady state errors to first order. The procedure is simple in use, whether the assumption employed is a quasi steady state assumption [21,22], a rate-controlled constrained equilibrium assumption [38], or an assumption of redundancy as demonstrated below.…”

“…It is fast and hence particularly attractive when there is a strong need for a flexible degree of reduction, e.g. when adaptive chemistry is employed [22].…”

The use of dynamic adaptive chemistry in combustion simulation of gasoline surrogate fuels

“…Most of the AC methods proposed in the literature [20][21][22][23][24] pre-generate a library of reduced mechanisms. Each submechanism in this library is valid over a range of the overall thermochemical conditions expected to be encountered in a given reacting flow calculation.…”
