Agitated Vessels for Heat Transfer Enhancement
Agitated vessels for heat transfer enhancement are jacketed or coil-equipped mixing systems where agitation improves heat transfer between process fluid and heat transfer surfaces. These vessels provide efficient heating or cooling through optimized fluid motion that minimizes thermal boundary layers.
Why are Agitated Vessels Needed for Heat Transfer Enhancement?
Heat transfer in jacketed vessels is limited by the process-side film coefficient, which agitation dramatically improves. Proper mixing eliminates stagnant regions, reduces boundary layer thickness at heat transfer surfaces, and ensures uniform temperature throughout the batch. Enhanced heat transfer reduces cycle times and improves temperature control.

Agitated Vessels for Heat Transfer Enhancement FAQs
How much does agitation improve heat transfer?
Agitation typically improves process-side heat transfer coefficients by 5-20 times compared to natural convection. The improvement depends on impeller type, speed, and placement. For viscous products, scraped-surface agitation provides dramatic improvement. Overall heat transfer improvement is significant but depends on limiting resistance location.
What designs maximize heat transfer?
Heat transfer optimization uses impellers positioned to direct flow toward heat transfer surfaces, baffles that promote wall sweeping, and adequate power input. For viscous products, close-clearance impellers with wall scraping maximize heat transfer. CFD analysis optimizes flow patterns for heat transfer performance.
