On HTRI spiral baffle heat exchangers
Thread Content
Currently, water vapor is used to heat the water, and a falling film heat exchanger is employed for HTRI calculations. However, when using baffle plates, the heat transfer coefficients calculated for ordinary arc-shaped baffles and single or double spiral baffles are essentially the same. Is this normal, or is it necessary to use additional software for the design? Please help, experts~~:lol
Spiral baffles and conventional arc-shaped baffles generally differ in heat transfer efficiency, as the spiral shape can increase the turbulence of the fluid, thereby enhancing heat transfer efficiency. If the calculation results are similar in the HTRI software, it may be due to errors in parameter settings or model selection. It is recommended to carefully check the input parameters, such as flow rate, temperature difference, and material properties, to ensure their accuracy. If the problem persists, consider using other professional heat exchanger design software for comparative verification, or seek the advice of more experts. .
For the water vapor flowing in the shell side, during calculations, the impact of the baffle structure (within an appropriate range of values) on the steam condensation process is relatively small; you can adjust the temperature at the condensate outlet to see if there are any changes
