Теплообмен у трубчатого подогревателя морских наливных судов

Теплообмен у трубчатого подогревателя морских наливных судов

Abstract

The investigation of the heat exchange of the marine tankers' tubular heater made it possible to receive criterion equations for calculating average and local heat emission in free convection for a wide range of Raand Prnumbers taking into account the variable viscosity. The oscillations intensify the heat exchange process. The heat exchange process of tubular heater while tankers are tossing belongs to a stationary mixed convection. Three zones of oscillation influence on the heat exchange of the horizontal cylinder are formed, and the boundaries of these zones are determined. The criterion equation, which generalizes the heat exchange at vibration, oscillations, rotation and horizontal cylinder flow, is received.

Исследования теплообмена у трубчатого подогревателя морских наливных судов позволили получить критериальные уравнения для расчета средней и локальной теплоотдачи при свободной конвекции в широком диапазоне изменения чисел Ra и Pr с учетом переменной вязкости. Колебания интенсифицируют процесс теплообмена. Процесс теплообмена у трубчатого подогревателя при качке морских наливных судов (колебаниях) относится к стационарной смешанной конвекции. Установлены три зоны влияния колебаний на теплообмен у горизонтального цилиндра и определены границы зон. Получено критериальное уравнение, обобщающее теплообмен при вибрации, колебаниях, вращении и обтекании горизонтального цилиндра. Библиогр. 15. Ил. 3.
