Modeling and Design of a Solar Rotary Dryer Bench Test for Phosphate Sludge

Modelling and Simulation in Engineering, Volume 2022, Issue 1, 2022., 2022
As an eco‐friendlier way to manage mining waste, the use of solar energy to dry phosphate sludge in a rotary dryer is envisioned. As a first step toward this end, a design study for a bench‐scale rotary dryer for phosphate sludge is detailed, using a one‐dimensional mathematical model developed for this task. Using the Engineering Equation Solver (EES)

Agricultural water management challenges in the Hunza River Basin: Is a solar water pump an alternative option?*

Irrigation and Drainage, Volume 70, Issue 4, Page 644-658, October 2021., 2021
Abstract In the glaciated mountains of the Upper Indus Basin of Pakistan, glacier‐ and snowmelt‐ based irrigation systems have been established over several centuries to secure water for cultivation. However, these systems are now facing several challenges, being sensitive to climate change and thus exposed to the resulting extreme events such as ...

Smart grid lab research in Europe and beyond

International Journal of Energy Research, Volume 44, Issue 3, Page 1307-1336, 10 March 2020., 2020
The predominant category of smart grid research is identified to be generation and distributed energy resources (Gen & DER). Grid management and Gen & DER and energy storage and Gen & DER have been found to be popular combinations of topics. An overall increase in publications was observed over the past 11 years in virtually all categories of smart ...

Experimental Investigation of Thermal Conductivity and Specific Heat of the Calcium Phosphate Ore for a Drying Application

Mathematical Problems in Engineering, Volume 2020, Issue 1, 2020., 2020
This paper discusses an experimental investigation to determine regression models for thermal properties of phosphate particles and to analyze the performances of the phosphate flash dryer. For this purpose, the specific heat capacity and thermal conductivity of phosphate particles were experimentally determined by the modulated differential scanning ...

New Strategies and Simulation Tools to Optically Design a Field of Heliostats

International Journal of Photoenergy, Volume 2013, Issue 1, 2013., 2013
A heliostats field is an array of mirrors concentrating the solar power on a receiver, typically placed on a tower. Our research experience in the optical design of heliostats fields for Concentrating Solar Power plants suggested using apposite simulation procedures, which were especially developed to simplify the reproduction of heliostats fields and ...
