Type of article: Article

Summary

DESCRIBES THE TECHNIQUE OF USING COLOUR CHANGE PAINTS -TEMPERATURE-SENSITIVE COMPOUNDS THAT UNDERGO ABRUPT CHANGES OF COLOUR WHEN THEIR TEMPERATURES ATTAIN PREDETERMINED VALUES -TO DETERMINE RATES OF CONVECTIVE HEAT TRANSFER. IDENTIFIES 5 FACTORS AFFECTING THE ACCURACY OF THE TECHNIQUE, LEADING TO MINIMUM ERROR IN THE ESTIMATED VALUES. APPLIES THE METHOD TO NATURAL CONVECTION ON A HEATED FLAT PLATE FACING DOWNWARDS IN WATER. COMPARES THE RESULTS WITH EXISTING DATA, QUANTIFIES ERRORS AND ESTABLISHES SPECIMEN PARAMETERS TO OBTAIN RELIABLE DATA. (INT. BUILD. SERV. ABSTR., GB., 23, N 1, 1988, 23, 88-00217.
