Numerical Simulation Study on Desorption∕Adsorption Processes in a Novel Thermochemical Reactor Based on Hydrated Salts
摘要
Abstract
To address the challenges associated with the direct analysis of heat and mass transfer mechanisms within reactors,as well as the insufficient stability of reaction processes,a novel sieve-plate thermochemical reactor has been designed.This reactor utilizes MgSO4 hydrate salt as the energy storage material,and the heat and mass trans-fer characteristics,along with operational performance during the reactor's energy storage process,have been thor-oughly analyzed.Initially,a three-dimensional multiphysics coupling model of the reactor was developed.Subse-quently,by comprehensively considering the conservation of energy,mass,and momentum,as well as reaction ki-netics,numerical simulations analyses were conducted to evaluate the temperature field,water vapor concentration,and reaction conversion rate during both desorption and adsorption processes.The simulation results indicate that the sieve-plate chemical reactor significantly enhances fluid distribution and the conditions for heat and mass trans-fer.During the desorption phase,the reactor temperature rises rapidly,while the water vapor concentration initially increases before subsequently decreasing.In the adsorption phase,the reactor releases heat steadily,with tempera-ture initially rising and then declining,accompanied by a uniform distribution of water vapor concentration.The re-actor achieves thermal efficiencies of 39.31%and 75.21%during the desorption and adsorption phases,respectively.关键词
