Objective: The present study was made to investigate the enhancement in the heat transfer characteristics of CuO water base nanofluids by inserting the baffles in the annulus of the double pipe heat exchanger. Statistical Analysis: The experimentation was carried out with distilled water and copper oxide water base nanofluids at 0.1% and 0.2% volume concentration. The effect on heat transfer coefficient and Nusselt number is determined in this experiment at various temperatures. Findings: It has been observed that in comparison to the distilled water, copper oxide nanofluids with baffles shows more heat transfer enhancement. The result showed that the Nusselt number increased by 8% without introducing baffles and nanofluids and 10-12% enhancement was observed with baffles and nanofluids. The enhancement of 22-25 % has been observed in the heat transfer coefficient at 0.1% volume concentration and 25-30 % of enhancement 0.2% volume concentration. Applications: In automobile radiators, cooling towers, air preheaters, refrigeration, air conditioning, condensers etc double pipe heat exchanger with baffles inserts can be easily implemented.Keywords

Objectives: The present research examine the mechanical properties and microstructure of aluminum alloy 63401 metal matrix composite reinforced with silicon carbide powder of different wt% i.e. 3%, 6% and 9% and different grain size. Different weight percent of SiC i.e. 3%, 6% and 9% with different grain size of 177 μm, 149 μm and 74 μm. Methods: The mechanical properties i.e. hardness, tensile strength and impact strength were studied by preparing the required samples by stir casting method. Findings: From the obtained results we found that more the weight percentage of SiC powder, impact strength, tensile strength and hardness increases but the percentage elongation decreases with increase in weight percentage of SiC and increases with decrease in grain size of SiC. Also microstructure shows the nearly distribution of reinforcement material. Applications: They can be used in making body parts of vehicles having great impact strength. Making different parts of aeroplanes and also used in producing bus bars of higher strength.Keywords

Objectives: This paper includes the study of mechanical properties and microstructure characterization of aluminium alloy 63401 reinforced with alumina powder of different mesh size and different weight percentage. Methods: Fabrication of composite material is done by stir casting process because it is the cheapest way to fabricate mass samples. Different grain size of (149μm, 74μm, 37μm) and different weight percentage of (3%, 6%, 9%) have been used in this experiment. Findings: The tensile strength, impact strength and hardness of the composite material produced by reinforcing alumina powder increases with increase in the percentage of alumina powder and also vary with particle size of alumina powder. Applications: This type of composite material can be used in aerospace and automobile sectors.Keywords

Big data analytics is used to examine large sets of data which may contain diversity of different types of data, it can be used to decrypt cryptic symbiology, correlating previously not known variables, finding the trends in the market, checking preferences of customers and finding out data about various businesses and institutions. The re-sult can be used to conduct informative market strategizing, checking out chances to generate higher income, to pro-vide effective consumer-oriented services, to improve effectiveness of operations and to provide competition-edge over competitors and other institutional profits. The main aim of Big data Analysis is to aid in better and informative decision making for the firms by taking advantage of capable data-scientists, genius model makers as well as other trained scientists to verify chunks of information that may be unused by the traditional programs. It may include ana-lyzing special log and internet based information, internet network data and social-analysis of reports. It can also be used to analyze network records, caller details and other information gathered and operated by IOT devices. It can be used to bind with big data and unstructured data as well as partially structured data.Keywords

In the present work, an attempt has been made to study the microstructural and mechanical behaviour of Mg-alloy prepared by powder metallurgy process. Highly pure Mg powder is used for the fabrication of Mg-alloy at different additive percentages. The investigation of constituent phases was successfully completed for the Mg-alloy using standard X-ray diffractometers. Scanning electron microscopy was used for the morphological studies. Tensile strength and percentage elongation of Mg-alloys were also evaluated at room temperature. The minimum and maximum ultimate stress varies from 67 to 108MPa. The percentage elongation also increased 1.03 to 1.57%.Keywords
