摘要

研究了复合材料成型过程中粘性化学反应液体在平面通道内的流动和传热。任务定义中的主要假设是基于液体的高粘度和低热扩散率。Brinkman方程被用作运动方程。这种流动伴随着化学反应,导致粘度急剧增加。粘度被认为取决于温度和转化程度。这反过来又导致在数学模型中包含了化学反应的动力学方程。能量方程采用单温度模型表示,并包含耗散热排放。求解了温度一阶边界条件下的问题。给出了努塞尔数分布和速度剖面变换的计算方法。采用有限差分迭代法对该问题进行了数值求解。

Flow of viscous reacting fluid through a porous filler in a flat channel
The flow and heat transfer of a viscous chemically reacting liquid in a flat channel during the molding of composite products are studied. The main assumptions in the task definition were made on the basis of the high viscosity of the liquid and its low thermal diffusivity. The Brinkman equation is used as a motion equation. The flow is accompanied by a chemical reaction, resulting in a sharp increase in viscosity. The viscosity is considered to depend on the temperature and the degree of conversion. This, in turn, led to the inclusion of the kinetic equation of a chemical reaction in the mathematical model. The energy equation is denoted using a single-temperature model and includes dissipative heat emissions. The problem is solved for temperature first-order boundary conditions. The calculations are given for the Nusselt number distribution and the velocity profile transformation. The task was solved numerically by the finite difference method using iterations.
