摘要：A meso-scale vortex combustor has been designed in order to common flame quenching problems in meso/micro scale burning. Numerical simulations using Computational Fluid Dynamic (CFD) Ansys Release 19.0 Academic program was performed to determine a stable combustion flame. Combustor chamber made from two steps, first step diameter 6 mm with 4 mm depth, second step diameter size 8mm with 5 mm depth. This simulation used mixture of propane fuel-air. The fuel is fed through two channels of fuel inlet with 2 mm diameter. The variable of fuel flow rate was investigated in order to get the boundary of extinction limit and blow off limit of flame (stable flame region). The results show that the flame stable limit by using meso-scale vortex combustor more widely than other types of micro combustor. Therefore, the meso-scale vortex combustor that was developed could be used to overcome the flame quenching problems.
