Experiment bench for heat transfer of ice slurry-seawater two-phase flow

Abstract

The invention discloses an experiment bench for heat transfer of an ice slurry-seawater two-phase flow. The experiment bench is composed of an ice making system, a power system, a control system and atest system, the ice making system includes an ice machine, an ice slurry groove and a seawater storage tank, an inlet of the ice machine communicates the seawater storage tank, and an outlet of theice machine locates above the ice slurry groove; the power system includes a mortar pump, an inlet of the mortar pump communicates the ice making system, and specifically communicates the ice slurry groove of the ice making system; an outlet of the mortar pump communicates an adjusting system; the test system includes a test pipeline, a vibration excitation device and a power source and two ends of the test pipeline separately communicate the adjusting system; a test section is arranged on the test pipeline, and the test section passes through a pipeline housing, and the pipeline housing is installed on the vibration excitation device. The invention has the following beneficial effect: the vibration excitation device is arranged on the experiment bench and is able to simulate vibration ofa ship when the ship is travelling, and a certain amplitude is applied on an experimental hose so that experimental work conditions and actual work conditions are closer to ensure the experiment accuracy and improve the reliability of experiment results.

Description

technical field [0001] The invention relates to a two-phase flow heat exchange test stand, in particular to an ice slurry-seawater two-phase flow heat exchange test stand. Background technique [0002] Ice slurry-seawater two-phase flow heat exchange is common in polar ships. When the polar ship is driving in the polar region, broken ice enters the seawater pipeline system of the ship, and accumulates inside to form a blockage, causing the ship's seawater cooling system to be paralyzed, and the temperature of the cooling water rises rapidly beyond its normal operating temperature range, causing the ship's equipment to fail to work normally , resulting in the failure of the entire ship power system. Therefore, it is necessary to discuss the change law of the heat transfer coefficient of the cold and hot fluid in the cooling system during the operation of the polar ship, so as to provide a reference for solving the problem of ice blockage in the current seawater pipeline syst...
