Experimentally investigated the fully developed laminar convective heat transfer and friction factor characteristics of different volume concentrations Al 2 O 3 nanofluid in a plain tube and fitted with different twist ratios of twisted tape inserts. Experiments are conducted with water and nanofluid in the range of , 2200 Re 700 particle volume(More)
We report a new type of magnetic nanofluids, which is based on a hybrid composite of nanodiamond and nickel (ND-Ni) nanoparticles. We prepared the nanoparticles by an in-situ method involving the dispersion of caboxylated nanodiamond (c-ND) nanoparticles in ethylene glycol (EG) followed by mixing of nickel chloride and, at the reaction temperature of 140°C,(More)

In spite of the advantages of ease of imaging and low acquisition cost, ultrasound images are noisier and have poorer image quality than other imaging modalities like CT or MRI and hence require an experienced clinician for interpretation. Processing by automated segmentation assists clinicians and improves the accuracy of assessment by minimizing its(More)
