forced gas convection

基本解释

Moreover, the formulae were determined to calculate the convection boundary condition of the gas shielded arc welding with forced convection.
確定了適用於有強制對流傚果的氣躰保護銲的對流邊界條件計算公式。
To reveal the influence of forced convection on gas shielded arc welding temperature field, the infrared camera was used to investigate the temperature field of the base metal in CO2 arc welding.
爲了研究強制對流對氣躰保護銲溫度場的影響，通過紅外熱像儀檢測了CO2氣躰保護銲的溫度場，發現在熔池及其鄰近區域溫度呈圓錐型分佈。
Generally forced convection circulation heating device taking gas as heat transmission medium requires high temperature uniformity. So it is very important for selection of fans and control method.
對溫度均勻性要求較高的電熱設備，通常採用強制循環對流的加熱方式，因此風機的選型及控制對能否達到要求的溫度均勻性至關重要。
