THE CALCULATION METHOD OF PVTT STANDARD TEMPERATURE AND PRESSURE VESSEL SIMULATION UNDER TWO KINDS OF BOUNDARY CONDITIONS

摘要：

　　CFD method was used to study the intake of the pVTt standard container under the two boundary conditions of constant wall and adiabatic wall,and the natural convection processes was simulated.The simulation results show that the average temperature of the air in the container is gradually changed inparabola and the stability time is long.Under the condition of adiabatic boundary condition,the average air temperature in the container is rapidly stabilized; the gas pressure under the two boundary conditions reaches uniformityquickly.The temperature,pressure distribution cloud diagram,and variation curve of the average temperature,average pressure were given and discussed.
