Boundary layer control and mainstream perturbation coordinated integrated enhanced heat transfer method and system

Abstract

The invention relates to the dehumidification drying field, and especially relates to and discloses a boundary layer control and mainstream perturbation coordinated integrated enhanced heat transfer method. Boundary layer flow control devices are disposed in a flow boundary layer, and a mainstream perturbation device is arranged in a mainstream channel to realize sufficient heat transfer. The invention also provides a boundary layer control and mainstream perturbation coordinated integrated enhanced heat transfer system. Multiple boundary layer flow control devices are longitudinally disposed on refrigeration end ribs close to a wall surface, the mainstream perturbation device is disposed in a flowing mainstream channel, and heating end ribs are also arranged in the same way. The superiority of the boundary layer control and mainstream perturbation coordinated integrated enhanced heat transfer system provided in the invention lies in that: through the brand new boundary layer control and mainstream perturbation coordinated integrated enhanced heat transfer method, cold and heat transfer impediment caused by the boundary layer can be overcome efficiently, and at the same time the limit that a mainstream short flow cannot be fully heated and cooled in traditional methods is broken, so that whole flow-field integrated high efficiency heat transfer can be formed. Thus, the method and the system provided in the invention are a brand new heat transfer enhancement method and system.

Description

technical field [0001] The invention relates to the field of dehumidification and drying, in particular to a method and system for enhancing heat exchange integrated with boundary layer control and mainstream disturbance. Background technique [0002] The rapid dehumidification and drying of humid air or other process gases is an important issue involving many fields from daily life to industrial applications. [0003] With the continuous improvement of people's quality requirements for air, food and medicine, the control of humidity in production and living environments has become a very important issue. For the industrial field, the existence of humid air and condensed water will directly lead to corrosion and failure of instruments and components, and even lead to failure of corresponding process systems. At the same time, humidity will inevitably lead to changes in the characteristics of process materials, which will have a negative impact on production. In daily life,...
