Wound Closure Techniques in Ayurveda: A Short Review

Journal of Medical Science And clinical Research (2015)

Anil Kumar Pratyush Kumar Narinder Singh

In surgical practice suturing is very important procedure.It is equally important procedure in both traumatic wound as well as in the elective surgery.Ayurveda is the most ancient medical science in our civilization.Ayurvedic acharyas has describes the Asthvidh Shalya Karma for various surgical disorders.Suturing i.e.Sevana Karma in one of them.Suturing is utilized for closing the wounds or/and ligating the bleeding vessels during surgery.Ayurvedic acharyas very well know the methods of suturing and its importance in practice and described well in various classical literature of Ayurveda.In modern day surgical practice we all follow the same principle without change.In present review study a humble effort is made to elaborate the ancient principle of wound closer.

Sustainability and Cost Effectiveness Analysis of Staggered Jet Impingement on Solar Thermal Collector

Energies (2022)

Rajesh Maithani Anil Kumar Manoj Kumar Sachin Sharma

The sustainability index, waste energy ratio and improvement potential of a staggered air jet impingement on the staggered spherical protrusions of a roughened absorber plate were derived for the present study to evaluate exergy losses and irreversibility in the system. The experimental analysis was carried out for selected parameters: relative streamwise pitch, relative spanwise pitch and relative jet diameter to hydraulic diameter ratio. The flow Reynolds number ranged from 4000–18,000. The augmentation in Nusselt number and friction factor compared to a smooth surface was 4.9 and 12.4 times, respectively. The statistical correlation developed determined the maximum thermohydraulic performance parameter and exergetic efficiency be 3.02 and 3.87%, respectively. The magnitude of the sustainability index, waste energy ratio and improvement potential was found to be 1.0347, 0.962 and 10.84, respectively, for the entire range of tested parameters. A cost analysis was also performed to evaluate the cost-effectiveness of the solar thermal system with and without turbulent promoters.

Experimental analysis of heat exchanger using perforated conical rings, twisted tape inserts and CuO/H2O nanofluids

Case Studies in Thermal Engineering (2023)

Anil Kumar Masood Ashraf Ali Rajesh Maithani Naveen Kumar Gupta Sachin Sharma

This research paper presents an experimental analysis on a heat exchanger tube using a newly designed perforated conical ring combined with twisted tape as inserts. The investigation analyzes various geometric and flow parameters in the experimental setup, including a wide range of Reynolds numbers, varying from 6000 to 30000, nanoparticle volume concentration (ϕnp) of 0.25-1.0%, the ratio of inlet flow dia to inner print dia of the ring (DIR/DBR) of 1.33-2.33, ring pitch ratio (RP/ DED) of 1.41-2.51, twist ratio (TL/ WT) of 3.33-4.38, with fixed values for other parameters: relative ring height ((DED/ WR) of 2.33 and nanoparticle diameter (dnp) of 30nm. The optimal result of the thermal-hydraulic performance parameter (ηTT) is 1.45 at DIR/DBR = 1.83, TL/ WT = 3.50 and RP/ DED = 1.76. For the CuO/H2O nanofluids flow heat exchanger tube with perforated conical rings, empirical correlations were developed for the Nusselt number and the friction factor. These correlations were established with a range of 9.0% and 8.0%, respectively.

Parametric optimization of impinging air jet on hemispherical protrusion of a solar thermal collector

Experimental Heat Transfer (2022)

Rajesh Maithani Rishabh Agarwal Anil Kumar Sachin Sharma

The parametric optimization of thermal collector having hemispherical protrusion with air jet impingement is carried on effective efficiency criterion. The parameters selected for the investigation are the relative spanwise pitch (Y/Dh), relative streamwise pitch (X/Dh), and ratio of the relative protrusion diameter to height (dpr/epr). A MATLAB program is executed to collect the data, and the optimization plots and table are prepared to determine the optimized parameter. For a wide range of operating parameter, the optimized values are relative streamwise pitch of 1.304, relative spanwise pitch of 0.434, and relative protrusion diameter to protrusion height ratio of 1.5.

Biodiesel Fuel Production by Methanolysis of Fish Oil Derived from the Discarded Parts of Marine Fish

Anil Kumar Sharanappa Godiganur R. P. Reddy

The world is on the brick of energy crisis. The limited fossil fuel sources are unable to fulfill increasing energy demand. The depletion of fossil fuels and augmentation of environmental pollution have lead to exploration of alternate fuels. Biodiesel (mono alkyl esters) synthesized from various vegetable and animal fat oils have proven as a potential resource and shown neutral effect on environmental pollution. Most research on biodiesel has focused on using plant based oil as feed stocks. There has been much less research on converting animal based oil into biodiesel. It has been estimated that over a million tons of fish by-products are generated from fishing industry. Some of these products are converted into fish meal and oil, but approximately 60% are not utilized. The major fish by-product includes fish head, viscera and some frame with of oil stored in the head. Fish by-product can also be converted in to hydrology-state through hydrolysis. The marine fish oil is identified as one such potential source of biodiesel as it can be extracted from the discarded parts of the marine fish which may provide an abundant, cheap and stable oil source. The present work emphasizes the synthesis of methyl esters from high free fatty acid marine fish oil and the optimization of process variables like volumetric ratio of oil to methanol, catalyst percentage, reaction time and temperature is done for the highest conversion efficiency by volume.
