The present research aims at providing a reliable model for the simulation of oscillating flames which are often discovered in industrial gas turbine combustors operating at lean premixed conditions. The paper presents a Large Eddy Simulation of an oscillating bluff-body stabilised flame with a probability density function model of the subfilter scale interaction. The results show good overall ...

Thermal energy storage is an essential technology for improving the utilization rate of solar and efficiency industrial processes. Heat release by dehydration rehydration Ca(OH)2 are hot topics in thermochemical heat storage. Previous studies have described different methods thermodynamic, kinetic, structural stability to improve density, rate, cycle stability, respectively. Here, mechanisms ef...

This paper presents the model to estimate heat release in fire compartment about four fuels, Douglas fir considering char formation and moisture content, methanol, methane and propane, with equivalence ratio Q on the basis of previous work and discusses about the difference of the combustion efficiency of them. As the result, calculated heat release of Douglas fir, methane and propane shows rel...

This paper considers the maximisation of conversion by manipulating the input flowrate for an exothermic second-order esterification reaction (propionic anhydride + 2-butanol) performed in a semi-batch reactor. Safety considerations impose bounds on the heat release rate in normal operation and on the maximum attainable temperature in the case of cooling failure. The optimal input flowrate is c...

Heat release rate (HRR) is the principal fire characteristic of materials. There are three known methods for measurement HRR (based on oxygen consumption, mass loss rate, and combustion products temperature rise). The method based consumption considered to be reference. However, this expensive a large part laboratories universities unavailable. simplest products’ rise. has fundamental problem w...
