20 as the index of hydraulic performance. It is found that the friction factors for all the TETs are greater than those for the smooth tube. e. friction factor values are high, say up to Reynolds number 15000, then onwards it decreases. TET No. 3 has demonstrated the greatest friction factors since it has the highest aspect ratio. In this experiment it is found that the inﬂuence of aspect ratio on the ﬂow resistance is more than the twist pitch. 3 Twisted Elliptical Tubes 29 Fig. 00 0 10000 20000 30000 40000 50000 60000 Re Chapter 4 Advances in Compound Techniques (Fourth Generation Heat Transfer Technology) Abstract The advances in heat transfer enhancement techniques in all its aspects have been dealt with.

Generally, ultrasonic equipment is used to intensively disperse the particles and reduce the agglomeration of particles. Making nano-ﬂuids using the two-step processes is challenging because individual particles tend to quickly agglomerate before complete dispersion can be achieved. This agglomeration is due to attractive Vander Waals forces between nanoparticles, and the agglomerations of particles tend to quickly settle out of liquids. In fact, agglomeration is a critical issue in all nanopowder technology, including nano-ﬂuids technology, and a key step to success in achieving high-performing heat transfer nano-ﬂuids is to produce and suspend nearly monodispersed or non-agglomerated nanoparticles in liquids.
