对海底悬跨石油管道泄漏后流场与温度场的耦合进行分析，建立二维多相流海底管道模型，给出合理的流体力学和热力学边界条件，利用有限元软件FLUENT进行数值仿真分析。分析结果表明：海底悬跨石油管道泄漏对周围海水的温度场影响明显，高温区域随石油上浮而向上扩展；泄漏介质在管道周围产生绕流运动，离开管道后出现“滴流”现象。
對海底懸跨石油管道洩漏後流場與溫度場的耦閤進行分析，建立二維多相流海底管道模型，給齣閤理的流體力學和熱力學邊界條件，利用有限元軟件FLUENT進行數值倣真分析。分析結果錶明：海底懸跨石油管道洩漏對週圍海水的溫度場影響明顯，高溫區域隨石油上浮而嚮上擴展；洩漏介質在管道週圍產生繞流運動，離開管道後齣現“滴流”現象。
