Experimental and Modeling of Tomato Slices Sorption Isotherms and Thin Layer Drying Kinetics for a Solar Drying Plant Design [PDF]

Iranian Journal of Chemistry & Chemical Engineering, 2023
In the present work, the sorption isotherms of tomato slices (TS) are obtained by the gravimetric method at different temperatures (50, 60, and 70 °C). After fitting the desorption curves, the Guggenheim-Anderson-de Boer (GAB) model is chosen as the most

VISproPT: A high-precision instrument for 3D shape analysis of parabolic trough panels [version 1; peer review: 2 approved, 1 approved with reservations]

Open Research Europe, 2023
In Concentrating Solar Power plants, reflective panels are used to redirect solar radiation towards a receiver. Because the panel shape drives the radiation distribution around the focus where the receiver is placed, the 3D measurement is fundamental to ...
