Abstract

Flow characteristic of cold fluid in supersonic combustion experiment table is studied through the method of computational fluid dynamics (CFD) numerical simulation, direct measurement of pressure transducer and TDLAS measurement. Characteristic parameters of temperature and pressure etc. of the flow field are obtained respectively under four work conditions, under which the total temperature and pressure of inflow is 782K and 7.2atm, 814K and 6.3atm, 850K and 6.2atm, 912K and 6.0atm. Results indicate that computational pressure of CFD numerical simulation adopting SIMPLE algorithm and k-e Realizable turbulence model is consistent with that of direct pressure measurement on each measurement position. However, since under the experimental condition, air heater combustion generated triatomic molecule, which would make the specific heat ratio lower than that of ideal gas model used in CFD numerical simulation, so the flow velocity is lower in experiments, but the pressure is higher. Temperature and pressure obtained from TDLAS measurement agree well with the analog simulation according to CFD results. Temperature deviation of the front and rear of experimental segment is 4.2% and 10%, while the pressure deviation is 5.3% and 1.4% respectively. It can be seen that TDLAS would be applied in fluid parameters’ measurement of supersonic combustion well as a kind of non-contact flow field diagnostic techniques.
