The study of turbulent flow structures in a wavy channel using direct numerical simulation
직접수치모사를 통한 Wavy Channel 내의 난류 유동 구조의 연구
Abstract
Sinusoidal wavy channel is one of the most commonly used devices in the industry for achieving mixing and heat transfer. Here we report on results obtained from the DNS of flow inside the wavy channel performed using the finite volume technique. As a primary stage to obtain the optimal design for heat transfer and mixing, this study observed the basic flow structures in a wavy channel. The mass flow rate is kept constant with friction Reynolds number of
