Heat transfer enhancement technology provides many advantages in heat exchanger applications.In the present paper, characteristics and pressure drops of absorber tube Parabolic Trough Concentrators with wire-coils inserts are investigated.Water is used as a fluid simulations carried out COMSOL Multiphysics® 4.4, for various flow rates water well different pitch values insert.It observed that introduction wire coils increases turbulence inside tube, thereby increasing Reynolds number hence...
Earth air heat exchanger (EAHE) systems are insufficient to meet the thermal comfort requirements in winter conditions. The low heating potential of such can be improved by integrating system with solar duct (SAHD). aim this paper is present a model estimate for EAHE and without SAHD. generated using TRNSYS 17 simulation tool validated against experimental investigation on an set-up Ajmer, India. experiment was done during season, where evaluated different inlet flow velocities, length depth...
Oxidative stress, driven by excess ROS, damages lipids, proteins, and DNA, leading to neuronal apoptosis inflammation, a key factor in neurodegenerative diseases. This study explored stigmasterol, bioactive phytosterol, with neuroprotective potential, revealing strong docking interactions, especially Keap1 (binding energy of −11.62 Kcal/mol). Stigmasterol formed two hydrogen bonds Ile258 Val305 Keap1, suggesting it could disrupt Keap1-Nrf2 potentially activating antioxidant responses...
This study experimentally explores the influence of inclination angle and wavy tape inserts on mixed convection heat transfer pressure drop in a solar air heater tube. Experiments at 15° 30° inclinations, with Reynolds numbers from 455 to 6059 reveal that increasing reduces drop. Transition vary flux levels: 3 kW/m2 (2528-3793), 2 (2520-3801), 1 (2627-3848). The Colburn factors laminar transition flow regimes shows distinct characteristics but converge turbulent flow. width ratio 0.8 wave...
Among the various heat transfer enhancement techniques employed in micro channels, use of wavy channels has been gaining popularity. In this study, numerical analysis different cross sections conducted by varying Reynolds number and amplitude waviness. Four sections, namely rectangular, circular, notched rectangular circular have considered study. The varied from 100 to 800. A three dimensional, steady state on these using finite volume method. results indicate that coefficient increases...
In the present work, an earth water heat exchanger (EWHE) has been designed for Pilani, Rajasthan (India). The system is and simulated in transient analysis tool TRNSYS (v17.0) by varying its operating parameters which includes mass flow rate, length, pipe materials diameter of buried pipe. depth-wise temperature soil also evaluated from simulation it found that depth 3.5 m sufficient burial. results show there inverse correlation between length EWHE outlet temperature. comparative study...
In the present paper, a novel cooling system for concentrating photovoltaic (CPV) which is termed as earth water heat exchanger (EWHE) modeled and simulated local conditions of Pilani, Rajasthan. The CPV temperature power output are obtained with respect to variation in mass flow rate fluid concentration ratio (CR). simulation results shows that maximum goes up 416.36 °C at 3 Suns without any cooling, while it reduced down 85.28 0.022 kg/s. drop increases increasing when operated EWHE closed...
Earth air heat exchanger (EAHE) systems are inefficient to provide thermal comfort in winter season for semi-arid regions. The performance of such could be improved by coupling them with other renewable energy sources. One the technology is rooftop photovoltaic/thermal (PV/T) collectors which utilize incident solar insolation obtain both electricity as well useful heat. In current paper, an EAHE coupled a PV/T system has been numerically investigated climatic conditions Pilani, Ajmer...
Cancer is a complex and widespread disease affecting various organs tissues, with an expected significant increase in reported cases. Current treatments like chemotherapy radiation therapy have limited efficacy adverse side effects. This study investigated the multi-target therapeutic potential of seven phytochemicals against critical cancer-associated proteins. Computational docking studies analysed binding interactions between proteins, supported by in-vitro experiments on cancer cell...
The operating temperature is an important factor affecting the performance and life span of Photovoltaic (PV) panels. rising can be maintained within certain limit using proper cooling techniques.
