“…One example is the metallic coating on heating surfaces. Few investigators like Bliss et al [4], Magrini and Nannei [5], Scurlock [6], Hsieh and Yang [7], Cieslinski [8], Rainey et al [9] and Kim et al [10] studied the boiling of liquids on metallic coated heating surfaces and observed a significant enhancement of the heat transfer coefficient. However, most of these investigations were confined to the boiling of water, refrigerants, cryogenics, etc.…”

This paper presents an experimental investigation on nucleate pool boiling of saturated methanol on uncoated as well as copper-coated mild steel heating tubes of various thicknesses at atmospheric and subatmospheric pressures. It also includes the effect of heat flux, pressure and coating thickness on the boiling heat transfer coefficient of coated tube surfaces. Heat flux was progressively increased from 15,670.20 to 43,151.57 W/m 2 in six steps and pressure from 23.02 to 98.68 kN/m 2 in five steps. Boiling characteristics on such surfaces are compared with those on uncoated ones. Also, a criterion for enhanced boiling of methanol on copper-coated tubes is described.

Zusammenfassung. Es werden Versuche beschrieben, die unter Bedingungen des Beh~iltersiedens an Heizfl~ichen aus Kupfer, Messing und rostfreiem Stahl durchgefiihrt wurden. Die siedende Fliissigkeit war Wasser. Mit den Versuchen sollte ein Einflufi der thermischen Eigenschaften der Heizwand auf den W~irmeiibergangskoeffizienten nachgewiesen werden. Durch die besondere Pr~iparierung der Heizfl~ichen gelang es, ihre sonstigen Eigenschaften unabh~ngig vom Werkstoff zu machen. Die Messungen ergaben eine Vergr6fiemng der W~irmeiibergangszahlen mit steigender W~irmeleitflihigkeit der Heizwand. Parallel durchgeflihrte Messungen yon Blasenfrequenz und Blasenabreigdurchmesser ergaben, dagder beschriebene Ein-flufS nicht an den Meehaaismus der Mikrofilmverdampfung gebunden ist, sondern vemrsacht wird dutch das yon den thermisehen Eigenschaften des Werkstoffs abhw unter den vorliegenden Versuchsbedingungen quasistationSre Temperaturprofil in der Heizwand.Abstract. Experiments are described, which had be performed under conditions of pool-boiling on heating-plates made of copper, brass and stainless steel. The boiling fluid had been water. The experiments should show the influence of the thermal properties of the heating-waU on the heat-transfer coefficient. The other properties of the heating-wall had been kept independent of the material by a special preparation of the heating-surfaces. The measurements gave higher heattransfer coefficients with higher thermal conductivity of the heating wall. Measurements of the bubble frequency and

“…A comprehensive review of such geometries was given by Webb (1981Webb ( , 1983. He classified these enhanced surfaces into two types: (1) coating of very porous material formed by sintering (Gottzmann et al 1971), brazing, flame spraying (Dahl and Erb 1976), electroplating (Bliss et al 1969;Albertson 1977), and (2) mechanically machined, chemically etched (Vachon et al 1968) or formed double reentrant cavities (Fujie et al 1977) to ensure continuous vapor trapping. Griffith and Wallis (1960) showed that cavity geometry for naturally occurring surface pits and scratches is important in two respects: the mouth diameter determines the wall superheat needed to initiate boiling, and the mouth shape determines its stability once boiling has began.…”

This paper reviews literature on conventional scale boiling enhancement techniques by means of reentrant cavities and discusses various avenues the knowledge obtained from that research can be used to enhance boiling in microchannels. Fabrication techniques developed by the Micro Thermal-Fluids Laboratory at Rensselaer Polytechnic Institute together with the Advanced Microsystems Materials Laboratory at McGill University are discussed and preliminary data are given. These results demonstrate the potential for improving boiling heat transfer characteristics in microchannels and introduce next generation microchannel heat transfer technology.
