Abstract: Flat plate solar collectors (FPSC) should meet durability requirements which are related to the equipment ability to resist aging and damage occurring during lifetime. To face durability issues, especially concerning to freezing and corrosion resistance, Brazilian flat plate solar thermal collector manufactures are embracing product lines with stainless-steel (SS) Leia mais…
Abstract: Optical methods of vibration evaluation comprise a very powerful tool in areas such as quality control and predictive maintenance. We propose and experimentally demonstrate a technique for out-of-plane, whole-field vibration analysis by studying the visibility decrease of projected structured light on vibrating surfaces. The light pattern formed by straight, Leia mais…
Abstract: The characterization of gaseous mixtures is an increasingly important issue in the fields of fuel analysis and aerosol research. Analyses by refractometry combined with refractive mixing rules are also powerful tools in this area. In this work a setup comprised by a six-laser interferometer and a vacuum system was Leia mais…

Abstract: This paper presents a thermodynamic and kinetic model for simulating calcium carbonate scaling in a tubularreactor under varying saline composition, temperature, and flow rate. Simulation results are compared withexperimental data obtained from a tubular reactor developed by the IPT and Petrobras. A mathematicalmodel based on thermodynamics and crystallization kinetics Leia mais…
