摘要
螺旋流的特性已逐渐从物理模型中被揭示出来 ,而运用数值模拟的方法研究圆管螺旋流速度场、压力场特性及其分布规律是解决工程运用螺旋流排淤的关键。本文采用交替方向的隐式格式 (即 ADI法 )离散方程 ,并利用追赶法求解代数方程组 ,得到了圆管螺旋流速度场、压力场的分布规律。
It is critical for resolving the engineering utilization of spiral flow to study velocity and pressure distribution by numerical simulation.The author Discrete equations are attanied by using Alternating Direction Implic(ADI) and equations are solved by using Tridiagonal Matrix Algorithm.The velocity and pressure distribution of spiral flow is attained.A reliable foundation for studying spiral flow in future is provided.
