This paper investigated the optimization, modeling, and effect of welding parameters on the tensile shear load-bearing capacity of double pulse resistance spot-welded DP590 steel. Optimization of welding parameters was performed using the Taguchi design of experiment method. A relationship between input welding parameters i.e., second pulse welding...

The chemical reactions widely operate in industries to enhance the heat transfer rate among the chosen domain. In the current article, we are going to observe an exothermic reaction of calcium oxide and water in a backward step tubular reactor with a cooled surrounded surface. The tubular reactor will be considered axisymmetric with an aspect ratio...

Energy use in the building is responsible for one-third of total carbon dioxide (CO2) emissions globally. Nearly half of the energy loss occurs through the building envelope due to heat transfer to/for the surroundings. Therefore, there is a need to design an optimum building envelope to reduce energy use in buildings that depend on several paramet...

Disposing of waste tires is a major environmental and economic issue. Different recycling methods have been studied to account for its re-usage. This project aims to evaluate the possible usage of shredded waste tires in thermal energy storage (TES) applications, whether they are sensible or latent materials. An experimental setup has been develope...

In this paper, the ow of a power law uid has been investigated for Newtonian and non-Newtonian uids with the temperature distribution in a rectangular channel containing a heated circular cylinder near the inlet with di erent blockage ratios. e generalized non-Newtonian power law model coupled with the energy equation is solved numerically, conside...
Article
An optimal energy management strategy is difficult for an efficient operation of hybrid renewable energy systems due to the instability of energy resources. The present study analyzes a hybrid PV-battery integrated with the pump-hydro-storage system (PHSS) utilizing the rainfall potential at various probabilities of power supply loss. Two configura...
Article
This paper presents analysis and optimization of standalone hybrid renewable energy system for powering a 3.032 kWh/day housing unit. The hybrid system is strategized to utilize harvesting rainfall and integrating a pumped-hydro storage with a solar photovoltaic-battery system. The optimization, using particle swarm optimization technique, is conce...

In this study, the economic and environmental impacts of insulation material are determined for different sizes of heating, ventilation and air conditioning (HVAC) duct. The optimum insulation thickness (OIT), energy-saving (ES) and payback period (PP) for HVAC duct are estimated using Life cycle cost (LCC) analysis. The analysis considers coal, na...
Article
Biomass gasification is a promising approach for bioenergy conversion. Usually, biomass gasification is facing interruption in feedstock supply due to seasonal availability of biomass. In biomass gasification, formation of tar also affects the gasification efficiency. Therefore, in this study, catalytic air co-gasification of two palm wastes (cocon...
Article
This study presents a developed assessment methodology for Photovoltaic-Battery power system featured with utilization of the dumbed power for secondary applications such as water pumping. Primary target is to meet the demand of 3.2 kWh/day for rural housing unit. The PV-Battery system size is determined by varying the number of PV's and Battery ca...
Article
An open wind flow test of seven Savonius models was conducted to explore the influence of design parameters on the performance and starting characteristics. The seven rotors are coded as Model 1 to Model 7, with various blade designs, number of blades, and number of stages. Results demonstrated that Model 1, a modified two-blade single-stage conven...
Article
S-rotors, which currently have numerous configurations, after the introduction of the early type by Savonius, are low-cost and simple devices used to harness wind energy for stand-alone power systems. Although the power coefficient of S-rotors is comparatively low, geometric parameters, such as overlap ratio, aspect ratio, number of blades, number...
Conference Paper
Full-text available
This paper presents and discusses results from an experimental investigation of three models of wind S-rotors. Models 1 is modified from conventional Savonius rotor with a single stage and zero offsets zero overlaps; model 2 is three blade single stage wind rotor, and model 3 is double stage conventional Savonius rotor. The three models were design...
