A water-curtain heating system for plastic greenhouses
Journal of Agricultural Engineering Research, 1992A possible alternative method of using power station waste heat has been investigated using a small-scale physical model and its performance compared with that predicted from thermodynamic principles. It employs a variation of the water-curtain surface-heating method first investigated experimentally by Canham in 1957.

Design of water curtain control system of underground water seal oil cavern
2009 IEEE International Conference on Intelligent Computing and Intelligent Systems, 2009Widely building of the large span underground water seal oil caverns must gradually propose more stringent requirements of the design level of oil caverns. The large span underground water seal oil cavern not only needs to rely on the natural conditions of the buried groundwater, but must also relies on the water curtain hole installed around the ...

Automatic Control Research on Water Curtain System of Underground Water Seal Oil Cavern
2009 Second International Conference on Intelligent Computation Technology and Automation, 2009The operating costs of a large-scale water seal oil cavern are a good deal of expenses. Water curtain can achieve a reasonable distribution of water seepage field to reduce the water inflow into the cavern by optimizing the arrangement of water curtain system.

The preset algorithm of the controlled cooling system with grouped water-curtain for plate
Proceedings of the 3rd World Congress on Intelligent Control and Automation (Cat. No.00EX393), 2002We study the preset algorithm of the steel plate with water-curtain grouped cooling system. Based on the temperature at the entry and exit of the water-curtain, and gauge, speed, grade of the cooled plate with the working water-curtain number, the flow rate and water-curtain distributed methods which are determined by the algorithm, can be compensated ...
