为了有效利用极地气垫破冰船的发动机余热，需要研究相应的数值模拟方法。本文基于计算流体力学方法及混合物多相流模型，对包括舱室和垫升风机在内的内外部流场，进行与热交换相关的流场和温度场数值模拟。结果表明，加热对于改善垫升风机的推进效率有利，可使舱室平均温度上升41.13 ℃，垫升风机内平均温度上升34.16 ℃，对于极地气垫破冰船舱室及垫升风机内平均气温的提升有显著效果。混合物多相流模型用于数值求解此类热交换问题的有效性得到了验证。
In order to effectively utilize the engine waste heat of polar air-cushion ice-breaker, it is necessary to study the corresponding numerical simulation methods. Based on the mixture multiphase model of computational fluid dynamics, the numerical simulation methods of flow field and temperature field related to heat transfer are studied for the internal or external flow pertaining to the cabin and centrifugal fans. It is shown that heating is beneficial to improve the propulsive efficiencies of the centrifugal fans; It can increase the average temperature in the cabin by 41.13 ℃ and the average temperature in the fan by 34.16 ℃, which has a significant effect on the increase of the average temperature in the cabin and the centrifugal fans of the polar air-cushion ice breaker. The effectiveness of the mixture multiphase model for numerically solving such heat exchange problems has been verified.
