Abstract

Based on the Fluent software, the initial temperature field distribution in cylindrical constant volume combustion bomb was simulated and compared with the experimental values to validate the numerical results. Results show that the temperature distribution of fluid in chamber exhibits a significant gradient that decreasing firstly and then rising along the gravity direction. With the increase of the overall temperature in the chamber, the non-uniformity of the temperature field gradually increases as well. When the heating band voltages are 90 V, 120 V and 150 V respectively, the maximum error of the identified initial temperature in chamber are 25 K, 40 K and 60 K respectively, and the maximum temperature difference of the fluid medium along the gravity direction reaches 14 K, 23 K and 35 K respectively. The fluid in the chamber flows along the inner surface of the glass windows and converges at intermediate bottom of the chamber. In addition, the numerical simulation results show that it is advantageous to improve the non-uniformity of the temperature field by uniformly distributed heater attached to the outside surface of the constant volume bomb or heating the optical quartz glass windows.
