The experimental apparatus is located at MNIT, Jaipur. To perform experiments in forced convective heat transfer at mass fluxes from 400 to 1000 kg/m2-s, heat fluxes from 0.1 to 0.5 MW/m2 and percent Al2O3 volume fraction varying from 0.25 to 1% At constant pressure 1 bar and environmental temperature for investigating the convective heat transfer characteristics of Al2O3/water nanofluid and to extend the available database and report information on heat transfer characteristics of Al2O3/water nanofluid in an annular test section with an inner heating surface. Forced flow conditions and particle migration is suggested to be an important mechanism. The results of the present investigation are summarized as follows: i. This study revealed that heat transfer increases with increase in mass flux at all given ranges of percent Al2O3/water nanofluid and heat fluxes. ii. The results of this experimental work shows that heat transfer increases with heat flux applied. iii. Heat transfer increases with addition of the Al2O3 nanoparticles in the base fluid.

Using Taguchi method total experiments are required are L16 which are simulated in ANSYS FEM solver (Version-14.5). Proper FEM simulation techniques are applied for these simulation cases and the modeling steps are also developed for this research study. After proper simulation of these cases two responses are selected to optimize this base design for further study. The two response selected from this study is von-misses stress and body weight. In present study various type of analysis is performed both cases like signal to noise ratio analysis, analysis of variance analysis, model equation generation, optimization of this model equation for stress and body weight of hip joint. Visual analysis is also present in this research study. All these major outcomes are present in this research study. Rank identification of factors are also present in this study. The signal to noise ratio analysis for stress shows that the best factor is ball diameter whereas worst factor is neck length of hip joint.
