Spirally fluted horizontal tube falling film evaporator research , design spirally fluted horizontal tube falling film fuel atomization , will be applied to the micro - heater combustion chamber , with a one-time form a fuel vapor and conducive gas mixing , the mixing required small space, a short time a huge advantage. Selected for this micro- combustion mechanism of the combustion chamber reasonable ignition , ignition timing and ignition position , successful ignition and stable combustion . With the same power as the 2kw Stainless Steel Simian Network evaporation heater , compared with the evaporation effect , the ignition time is short , high combustion efficiency, easy to clean carbon deposits . Numerical calculation of the geometric model and precision of the whole three-dimensional full-size grid model for the complex structure of the heater inside and outside . Fluent software platform, using RNG k-ε turbulence model and standard wall function , PDF combustion model , droplets of discrete phase model the heater machine experimental model flow , combustion and combustion chamber with an external heat transfer process simulation reveals the speed of the combustion the indoor gas flow process , the temperature and group concentration distribution , compared with the experimental results show that the simulation results with a reasonable engineering precision . According to the numerical results , the heater performance may impact structural parameters were analyzed , combined with orthogonal design method , for CFD orthogonal test , pick out a significant impact on the structural parameters of the heater performance .
