Abstract

유체가 빙점온도이하로 일정하게 유지되는 두 평행판사이를 흐를 때, 시간에 따른 응고현상을 수치모사와 실험을 통하여 살펴보았다. 시간에 따른 얼음층의 성장이 쉽게 관찰되는 두 평행판을 설정함으로써 실제의 응고형태를 관찰할 수 있었으며, Lagrangian interpolation식을 적용한 수치모사실험을 한 바, 기존의 원통관에서 실험치와 이론해가 15∼50 % 정도의 오차를 보였던 것에 비하여 본 연구에서는 four-point interpolation을 적용한 경우 10 % 정도의 오차를 보이는 결과를 얻었다. 유체의 응고에 영향을 미치는 요인 중에서 유입온도나 유입유속에 비하여 벽면온도가 보다 중요한 역할을 함이 분석되었다.
The transient freezing of a liquid flowing between two parallel plates is investigated numerically and by visual experiment keeping the wall temperature constant under the freezing point of the fluid. The numerical solution is based on the Lagrangian interpolation equations at the moving boundary. The discrepancy of the numerical calculation from the experiment is of the order of 10 % based on the four-point interpolation method. The wall temperature plays more significant role on fluid solidification than that of inlet fluid temperature and average inlet velocity.
