| Zusammenfassung: | The invention provides a numerical simulation method of a double-screen standard temperature sensor based on CFD (computational fluid dynamics). The numerical simulation method comprises the following steps: modeling and naming a computational domain of the double-screen standard temperature sensor; carrying out grid division on a computational domain model of the double-screen standard temperature sensor; carrying out primary field simulation solution on the CFD flow field of the double-screen standard temperature sensor; outputting the incoming flow total temperature of the double-screen standard temperature sensor and the wall surface temperature of the ball bonding solid; outputting the ball bonding solid wall surface temperature of the double-screen standard temperature sensor; and outputting the ball bonding solid wall surface temperature of the double-screen standard temperature sensor, and calculating the speed error, the heat conduction error, the radiation error and the temperature measurement devia |
