Lake reservoir water temperature stratification simulation method based on natural heat conduction

Abstract

The invention discloses a lake reservoir water temperature stratification simulation method based on natural heat conduction. The lake reservoir water temperature stratification simulation method comprises the following steps that according to the characteristics of water temperature distribution of an actual stratified lake reservoir, the needed height of a water body on a lower isothermal layer of a model reservoir is determined according to a certain ratio; on the lower layer, with the needed height, of the model reservoir, N-1 annular air conditioning evaporator condenser pipes are perpendicularly and evenly distributed, and each annular condenser pipe is connected with an air conditioner host; clean water is injected into the model reservoir until the depth of water in the model reservoir reaches a certain value; according to the needed water temperature of isothermal layers, the temperature values of temperature sensors are set; the air conditioner host is turned on, the water on the lower layer of the model reservoir is refrigerated through the N-1 condenser pipes, the temperature of the water body on the lower layer is measured actually through the corresponding temperature sensor, the air conditioner host is automatically turned on of turned off according to feedback of the temperature sensors until the temperature of the water body on each isothermal layer is even and reaches a designated value, and then simulation is ended. By the adoption of the lake reservoir water temperature stratification simulation method based on natural heat conduction, the formed stratified water body has the advantages that the water temperature stratification is stable and the water temperature is even at the same water level.

Description

【Technical field】 [0001] The invention belongs to the field of water quality pollution control of lakes and reservoirs, and relates to a pilot test study on layered lakes and reservoirs, in particular to a reservoir water temperature layering simulation method based on natural heat transfer. 【Background technique】 [0002] The water temperature of deep-water lakes and reservoirs has obvious seasonal characteristics of layered distribution along the depth. In summer, a typical water temperature layered structure of variable temperature layer, thermocline layer and isothermal layer is formed from top to bottom, and the surface water temperature and bottom water temperature are very different. , Sometimes the temperature difference can reach about 20°C. When the water temperature of the lake is stratified, the water temperature gradually decreases and the density gradually increases from top to bottom. When the surface water temperature and the water body with high dissolved ox...
