A new experimental technique to determine heat transfer coefficient and pressure drop in smooth and micro-fin tube
An experimental test facility is designed and built to calculate condensation heat transfer coefficients and pressure drops for HFC-134a in a 10.21 mm ID smooth and 8.56 mm ID micro-fin tube. The main objective of the experimentation is to investigate the enhancement in condensation heat transfer coefficient and increase in pressure drop using micro-fin tube for different condensing temperatures and further...

Calibrating the multiple orifice mathematical model using physical scale model foam at low Reynolds number
Recently, gelcast ceramic foams are being considered as potential diesel particulate filter substrates. Consequently, a mathematical model known as the Multiple Orifice Mathematical (MOM) model for the study of fluid flow and the determination of pressure gradients across the foam filters was developed and calibrated by some researchers. However, there was need to establish the model application on a wider...
