Numerical (CFD) studies in twisted square duct

CFD analysis of steady fully developed laminar flow inside twisted duct of square cross section flow area is studied for Re range of 100 - 2000. A commercially available software is used for the analysis. Twist ratio used are 2.5, 5, 10 and 20.Maximum average f.Re values were observed for a twist ratio of 2.5 and Re of 2000. It is observed that the average f.Re values are not constant rather are function of Re and twist ratio. Average f.Re values are correlated with swirl parameter. Local distribution of f.Re across a cross-section is further analysed. Comparison of average f.Re values of twisted square duct with straight square duct is also done. Keyword: Twisted duct, laminar flow, twist ratio, Periodic flow, swirl parameter.

Experimental Studies in Plate Heat Exchanger

At present plate heat exchanger’s (PHE’s) are being used extensively in the chemical, process and allied industries due to their numerous advantages. Heat transfer and associated frictional pressure drop in PHE are investigated experimentally in this study. The applied PHE is 14 plate, 2 fluid and single pass-flow heat exchanger in which fluids flow in counter flow direction. Heat transfer and pressure drop data were obtained for water flow rates varying between 0.0168 kg/s to 0.3378 kg/s. In this flow range increasing flow rates from 0.0168kg/s to 0.3378 kg/s (Increase in Reynold number from 85 to 1640) caused an increase in the pressure drop from 88 Pa to 10957 Pa. Empirical correlations are proposed to correlate the present data for the heat transfer coefficient and friction factor in terms of Reynolds number and Prandtl number.

Regional environmental assessment status of granite mining in Karimnagar districts

Granite is a minor mineral; it is a major contributor in foreign exchange earnings. India is the second largest exporter of raw granite after China and ahead of Brazil and South Africa. India ranked fifth in the export of processed (value added finished) product. Granite contributed 4.51% exports value of all ores and minerals in 2007-08. The exports value of granite was next to diamond and iron ore during 2007-08. (IMYB-2010). Telangana State is one of the important Granite producing states unique varieties are Jet black granite of Warangal and Khammam districts and Tan brown variety of Karimnagar district. Mining operations are Manual, Semi-Mechanised and Mechanised. Dimensional stone mining generates enormous waste, sometimes upto 75% to 85%. Land degradation is due to voids created by mining; Creation of external waste dumps, areas covered by site services, plant and colony etc.

Fibonacci sequence in music

Music, with its harmonious melodies and rhythmic patterns, has the power to soothe the mind and delight the ear. Within the realm of Hindustani classical music, the core elements include raags, sargams, alaps, and tans, which have played a significant role in not only shaping my life but also in creating some of my happiest memories. For approximately six years, I have dedicated my time to studying various musical genres, with a specific focus on Hindustani classical music. I derive immense enjoyment from this passion, occasionally picking up the guitar and keyboard, and actively participating in my school's choir. However, music is much more than what meets the eye; it encompasses a broad spectrum of sounds, from the tinkling of chimes to the soothing rush of crashing waves.

Keyword-Based Search Engine Using Cosine Similarity

The development of search engines that can retrieve relevant content based on user-specified keywords is necessary due to the increasing volume of digital information available on the internet. In this abstract, a novel approach is presented to build a keyword-based search engine that uses cosine similarity to enhance search result relevance and precision. Our search engine, which is keyword-based and uses cosine similarity, has several benefits over traditional search engines. The accuracy of search results is improved by taking into account semantic relationships between words, leading to a more contextually relevant ranking. With increased precision and efficiency, users can expect better search experiences when searching for the information they need.

Study of statement on temperature and rainfall of Maharashtra, year 2022.

In dry farming areas, rainfall is considered to be an important ecological input to determine the farming types as well as its efficiency. This weather element also describes the surface and sub surface water resources of a region. In view of deterministic influence exerted by rainfall on agriculture especially in dry areas, the present paper attempts to present the rainfall and temperature distribution in Maharashtra. The analysis has been made at rain-gauge station level for the year 2022.
