Type of article: Article

Summary

THE HEAT TRANSFER IN POOL BOILING ON SURFACES WITH CAPILLARY STRUCTURES IS MUCH BETTER THAN ON PLANE SURFACES. IN THE PAPER AN ATTEMPT IS MADE TO EXPLAINTHE BOILING PROCESS IN CAPILLARY STRUCTURES. CONSIDERATION IS BASED ON A STUDY OF THE EQUILIBRIUM OF VAPOUR BUBBLES IN CAPILLARIES. IT COULD BE SHOWN THAT THE LIQUID SUPERHEAT FOR BUBBLES IN CAPILLARIES CAN BE CONSIDERABLY REDUCED IN COMPARISON TO THE SUPERHEAT NEEDED FOR THE EQUILIBRIUM OF THE SAME BUBBLES IN THE LIQUID WITH A PLANE VAPOUR-LIQUID INTERFACE. AS A CONSEQUENCE THE DRIVING TEMPERATURE DIFFERENCE WITH BOILING IN CAPILLARY STRUCTURES DECREASES, AND THEREFORE THE HEAT TRANSFER INCREASES.
