Description

An ice slurry-seawater two-phase flow heat exchange test bench technical field The present invention relates to a kind of two-phase flow heat exchange experimental bench, specifically a kind of ice slurry-seawater two-phase flow heat exchange experimental bench. Background technique [0002] Ice slurry-sea water two-phase flow heat exchange is relatively common in polar ships. When the polar ship is traveling in the polar regions, the ice fragments enter the ship The seawater piping system is constantly accumulating inside to form blockages, which leads to the paralysis of the ship's seawater cooling system and the rapid cooling water temperature. The speed rise exceeds its normal operating temperature range, causing the ship's equipment to fail to work properly, and ultimately causing the entire ship's power The system cannot operate. Therefore, it is necessary to measure the change of the heat transfer coefficients of the cooling and hot fluids in the cooling system ...

AI Technical Summary

Problems solved by technology

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 , eventually causing the entire ship power system to fail to operate
