Modified Single-Blow Technique for Performance Evaluation on Heat Transfer Surfaces
Keyword(s):
The existing single-blow, maximum-slope transient technique has been commonly applied for determining heat transfer performance of heat exchanger units or surfaces. However, results lack in accuracy and technical difficulties arise when it is applied to heat exchanger surfaces or units with NTU value smaller than 3.5. In the present paper, a modified single-blow technique is developed which can be applied to systems of any NTU values. Both theoretical analysis and experiments are performed. The validity of the present technique is borne out by the good agreement between experimental data and the existing theoretical solutions.
