Five locally available biomassesnamely Bamboo (Banbusea Tulda), Gulmohar (Delonix regia), Neem (Melia Azedarach L), Dimaru (Ficus lepidosa wall), and Shisham (Delbergia sissoo) had been characterized with CHN analysis. The elemental characterization results were used to model a downdraft gasification (10 kWthermal) process in terms of producer gas composition. A thermodynamic equilibrium modelling presentedfor throated gasifier, based on constants appropriate assumptions. compositions the...
Green tea leaves are dried partially at low temperatures (withered) after harvest. The present study evaluated the energy, exergy, economic and environmental aspects of a solar energy based laboratory-scaled withering trough. trough was coupled with air heater having an absorber plate protruded waste Al-cans. temperature within maintained around 35 °C. airflow rates considered were 0.03, 0.04 0.05 kg/s. maximum thermal efficiencies computed for SAH these mass flow 52.58% radiation 747 W/m2,...
Impinging jets are commonly used to enhance heat transfer in modern gas turbine engines. blade cooling typically operate at lower Reynolds numbers the range of 10,000–20,000. In combustor liner cooling, can be as high 60,000. The present study is aimed experimentally testing two different styles jet impingement geometries backside cooling. higher lead increased overall characteristics, but also an increase crossflow caused by spent air. air has effect rapidly degrading downstream numbers....
Experiments and numerical computations are performed to investigate the convective heat transfer characteristics of a gas turbine can combustor under cold flow conditions in Reynolds number range between 50,000 500,000 with characteristic swirl 0.7. It is observed that field characterized by an expanding swirling flow, which impinges on liner wall close inlet combustor. The impinging shear layer responsible for peak location augmentation. as increases from 500,000, augmentation ratio...
In the present analysis, a novel four-mode solar dryer was developed and tested for drying of Garcinia pedunculata. The four combinations considered were indirect-mode without storage (ID-WOS), mixed-mode (MX-WOS), with (ID-WS), (MX-WS). feature this that sets it apart is its capability to convert cabinet into various modes simply by sliding walls sides cabinet. system made space efficient, filling gravel up surface absorber plate inside air collector. For ID-WOS, MX-WOS, ID-WS, MX-WS,...
Tea is one of the most popular beverages around world. India accounts for 31% production globally. contributes 1% GDP country. The two major issues related to tea industry are energy and environment. processing intensive as various stages consume in form thermal or electrical energy. costs constitute 30% total costs. Various data consumption cost incurred analysed a Assam, compared with that South Indian industries. analysis shows 43% higher than consumed required process about 42% 58%...
Using distributed MEMS pressure sensors to measure small flow rates in high resistance fluidic channels is fraught with challenges far beyond the performance of sensing element. In a typical core-flood experiment, which may last several months, flow-induced gradients are generated porous rock core samples wrapped polymer sheath. Measuring these along path requires resolution measurement while contending difficult test conditions such as large bias pressures (up 20 bar) and temperatures 125...
Modern dry low emissions (DLE) combustors are characterized by highly swirling and expanding flows that makes the convective heat load on gas side difficult to predict estimate. A coupled experimental–numerical study of flow inside a DLE annular combustor model is used determine distribution transfer liner walls. Three different Reynolds numbers investigated in range 210,000–840,000 with characteristic swirl number 0.98. The maximum coefficient enhancement ratio decreased from 6 3.6 as...
We have performed measurements of the low-frequency spectra refractive index and extinction coefficient solutions acetone in cyclohexane at concentrations ranging between 27 135 mM by using terahertz time-domain spectroscopy (THz-TDS) room temperature. verified Beer's law for concentration range our experiment, which establishes fact that solute-solvent interaction has a significant contribution to observed spectra, whereas solute molecules is negligible present experimental conditions....
In this study, the thermos-mechanical characteristics of bamboo fiber-reinforced epoxy polymer composites made by compression molding and hand lay-up techniques are discussed. A lab-scale machine was fabricated for purpose using scrap materials Central workshop Tezpur University, India. To find suitable NaOH concentration fiber strip treatment, strips were treated with 5, 8, 12, 15 wt.% solutions 12 h in each sample. It is determined that optimal fabrication single tensile test, pull-out...
