Research on Double-Stream Coil-Wound Heat Exchanger

Abstract:

A calculation method for double-stream counter-current coil-wound heat exchanger is presented for methanol-methanol heat exchange process. The numerical simulation method is applied to determine the basic physical parameters of double-stream spiral pipes. A recycling methanol cooler is designed and calculated by numerical simulation and programmed iterative calculation. The calculation data is analyzed by comparing with different variables. The result shows that the introduction of numerical simulation can simplify the pipe winding process and accelerate the calculation and design of overall configuration. This method can be used for physical modeling and heat transfer calculating of spiral pipes in double-stream coil wound heat exchanger, program to calculate the complex heat transfer changing with different variables and optimize the overall design and calculation process of double-stream spiral pipe bundles.
