TL;DR: In this article, the influence of temperature (31-45 °C), particle concentration (< 2 vol %) and ultrasonication on the viscosity of sand-ethylene glycol-water dispersions was investigated.
Abstract: Experiments were carried out on the preparation and characterization of dispersions of sand in ethylene glycol-water (50-50%) mixture. The dispersions were prepared by stirred bead milling of 20-30 μm sand (in water) followed by dilution with water and ethylene glycol. The influence of temperature (31-45 °C), particle concentration (< 2 vol %) and ultrasonication on the viscosity of sand-ethylene glycol-water dispersions was studied. The thermal conductivity of dispersions as a function of particle concentration and ultrasonication has also been investigated. Correlations were developed for the prediction of relative viscosity and thermal conductivity ratio of the dispersions. Our results indicate that the sand-ethylene glycol-water dispersions, prepared by stirred bead milling and ultrasonication, have potential as coolants.

Abstract: The present work uses a scale down industrial pneumatic conveying and drying system in order to develop control-oriented models and suitable robust control strategies for the air preheating furnace of the system. A better control system has been achieved by utilizing the benefits of integrating first principle models, system identification techniques and parametric robust control methods. Though these processes are widely used in drying and transmission of different food, pharmaceutical and industrial products in the form of powder like fine-grained material, but suitable control oriented thermal models for these processes have not been studied. In the work the air preheating furnace of a pneumatic conveying and drying system is initially modeled with first principles. The novel dynamic models derived from first-principles is intended to evaluate dynamic changes in outlet air temperature corresponds to changes in current input to heating coils, air flow velocity and ambient temperature. Then a continuous ...
