Background COVID-19 is a disease affecting various human organs and systems, in which the virus seeks to interact with angiotensin-converting enzyme 2 receptors. These receptors are present in the oral cavity, but the direct relationship between such

Optimum operational conditions of hybrid photovoltaic-thermal systems
Autor: Douglas Bressan Riffel, Jose Aguiar dos Santos Junior, André L. M. Costa
Publikováno v: Energy for Sustainable Development. 60:26-32
The aim of this paper is to present a novel concept for control of hybrid photovoltaic-thermal systems: a Maximum Exergy Point Tracker. It operates by evaluation of the exergetic and energetic performance of a solar photovoltaic-thermal (PV/T) system

On the Friction Conditions in FEM Simulations of Cold Extrusion
Autor: Henry Valberg, André L. M. Costa, Uilian Souza da Silva
Publikováno v: Procedia Manufacturing. 47:231-236
Friction is a very important issue for calculating the punch force and energy consumption in cold extrusion. FEM simulations are commonly used to investigate this process, but the choice of the friction’s model and set-up parameter have influence o

On the mechanism of formation of back-end defects in the extrusion process
Autor: Henry Valberg, Martin Lefstad, André L. M. Costa
Publikováno v: Procedia Manufacturing
FEM-analysis is applied to study metal flow in aluminum extrusion with focus on how material flow defects form when the last part of the billet is extruded through an axisymmetric die. First, an overview is given of the current state of art of knowle

The hot spot in Al-rod extrusion investigated by FEM-analysis
Autor: Henry Valberg, André L. M. Costa, Martin Lefstad
Publikováno v: AIP Conference Proceedings
FEM-analysis is applied to study thermo-mechanical conditions in an industrial Al-rod extrusion process using long billets as stock material. In the analysis, focus is on the conditions in the hot spot present inside the metal of the billet material
