Abstract: The digital twin (DT) is a virtual replica of real-world buildings, processes, structures, people, and systems created and maintained to answer questions about its physical part, the physical twin (PT). In the case of the ...

Abstract: The present study investigates bubbly two-phase flow in a hydraulic jump using a flow visualization technique. Bubbly two-phase flow is encountered in many engineering problems; however, mainly ...

Abstract: This paper presents a haptic system the authors have developed for shape exploration in the field of industrial design. The system consists of a novel haptic-based digital technology, allowing ...

Abstract: In the last several years, gasification has become an interesting option for biomass utilization because the produced gas can be used as a gaseous fuel in different applications or burned in ...

Abstract: Steam methane reforming is the most common process for producing hydrogen in the world. It currently represents the most efficient and mature technology for this purpose. However, because of ...

Abstract: In the last several years greenhouse gas emissions, and, in particular, carbon dioxide emissions, have become a major concern in the power generation industry and a large amount of research ...

Abstract: Explicit closed-form expressions for the velocity, depth of ablation front, and penetration of the thermal profile valid up to a Stefan number of 30 (the vast majority of technological materials have a value below 10) and ...

Abstract: Abstract. This work presents an analysis of transient conduction heat transfer in a semi-infinite solid with uniform surface heating of intensity varying as a Gaussian, without a physically meaningful start. Practical and ...
