Abstract

The paper presents the results of the study of effective turbulent heat transfer along a rod bundle at its transverse streamlining, performed using the CONV-3D code based on the DNS approach. To determine the effective heat conductivity coefficient, the mixing of two plane-parallel coolant flows, moving at the same velocities and having different inlet temperatures in the working area was simulated. Comparison of the calculation results with experimental data for water has confirmed the usability of numerical modeling instead of real experiments. Such a replacement of a real experiment with its computational analogue is relevant for investigation of liquid metal coolants.

杆束横向流线处有效湍流传热的数值模拟

本文介绍了基于 DNS 方法的 CONV-3D 代码对杆束横向流线处有效湍流传热的研究结果。为了确定有效导热系数，模拟了工作区域内以相同速度运动且入口温度不同的两股平面平行冷却剂流的混合情况。将计算结果与水的实验数据进行比较，证实了用数值建模代替实际实验的可行性。用计算模拟代替实际实验对于研究液态金属冷却剂具有重要意义。
