摘　　要：采用正交边界拟合坐标变换模拟复杂的边界,全隐式耦合模型离散基本方程,矩阵追赶法求解代数方程组,建立了分叉型海湾温水排放数学模型.算例表明,包络图的方法评价温升影响范围,能够为工程设计和环境评价提供依据.A mathematic model for cooling water discharge to forked bays is established by using the boundary fitted orthogonal coordinate system to simulate the complex boundaries, the full implicit coupled solution model to discrete the base equations, and the matrix chase-after method to solve the algebraic equations. Examples show that the envelope method to evaluate scales of thermal pollution can be applied to assess the engineering design and environment.
