Significance Wildfires burn millions of hectares per year on every inhabited continent, but the physical mechanism governing spread is not known. Models wildfire are widely used for prediction, firefighter training, and ecological research have assumed various formulations known heat transfer processes (radiation convection) absent a definitive theory their organization. New experimental evidence reported here reveals how buoyancy generated by fire induces vorticity instabilities in flame...
Automotive coatings and the processes used to coat automobile surfaces exemplify avant-garde of technologies that are capable producing durable surfaces, exceeding customers’ expectations appearance, maximizing efficiency, meeting environmental regulations. These accomplishments rooted in 100 years experience, trial-and-error approaches, technique technology advancements, theoretical assessments. Because advancements directed at understanding how, why, when, where coatings, progress...
Many countries are planning their transition to renewable-energy-powered transportation sectors. Among those developing countries, like Jordan, which face financial burdens in the actual implementation due economic status. As penetration of electric vehicles increases, more green-charging stations will be required. Therefore, encourage investors initiate deployment phase, this work presents a better mapping and comparison method for Photovoltaic (PV) battery charging across Jordan. It...
The use of biogas fuel in homogeneous charge compression ignition (HCCI) engines has been promoted recently due to the environmental advantages. However, hydrogen sulfide (H2S) forms a non-environment friendly content and impurity that its removal is associated with high costs. In this study, effect using HCCI under different operating conditions investigated shed light on best scenarios combustion, even presence H2S contents. A modified reaction mechanism introduced by considering reactions...
In the context of refining countries' transition plans toward 100% shares renewable systems in electric power grids by 2050, this study aims to investigate, for first time, potential covering increasing energy demand vehicles (EVs) using previously planned hybrid system (RES) Jordan, which comprised wind, solar photovoltaic (PV), and battery storage (ESS). The optimal RES sizing is revisited examine influence EV penetration percentages charging rates (normal, medium, fast) optimize periods...
Electrostatic rotary bell sprayers (ERBSs) are widely used in the automotive industry. In ERBS, atomization is facilitated using centrifugal forces which disintegrate paint film inside cup into droplets at edge. The then transported by flow of a shaping air (SA) and electrostatic to target surface; characteristics these dramatically influence quality painted surface painting transfer efficiency. current paper, novel Schlieren-based visualization absence was performed during qualitative...
Many developing countries suffer from high energy-import dependency and inadequate electrification of rural areas, which aggravates the poverty problem. In this work, Al-Tafilah in Jordan was considered as a case study, where technical, economic, environmental benefits decentralized hybrid renewable energy system that can match 100% city demand were investigated. A tri-hybrid wind, solar, hydropower integrated with an storage optimized to maximize between production profiles. The...
In this study, we evaluated the fundamental physical behavior during droplet formation and flow from a rotary bell spray in absence of an electrostatic field. The impact wide range operating parameters sprayer, such as rates, rotational speeds, spatial positioning, on sizes size distributions using three-dimensional (3-D) mapping was studied. results showed that increasing speed caused Sauter mean diameter droplets to decrease while rate increased sizes. effect, however, dominant compared...
The authors are a team of fire whirl researchers who have been actively studying whirls and large-scale wildland fires by directly observing them through fire-fighting efforts applying theory, scale modeling, numerical simulations in research. This multidisciplinary research-background previously conducted model experiments to reconstruct hazardous the laboratory, then developed fundamental theories translate these findings into basic understanding combustion science fluid dynamics. article,...
Abstract Background Online learning has recently surged due to the COVID‐19 global pandemic. Because of pandemic, many universities were forced move online learning, and various teaching environments emerged, both asynchronous synchronous. Objective This study explores how a large university in Southeastern United States America converted an in‐person Lean Manufacturing professional course into synchronous for industry participants. Method The analysed performance 212 43 participants...
