Effect of plant structure modification and natural convection in solvent on the rate of supercritical extraction
TL;DR: In this paper, an Instantaneous Controlled Pressure Drop (DIC) was applied as pretreatment technique to enhance the supercritical extraction by structure modification of extracted material, and the most important effect of the treatment was observed in the case of soybeans.

Dense Granular Flow as Heat Transfer Media: A New Type of High Power Target Design
Xuezhi Zhang,Lei Yang +1 more
TL;DR: In this paper, a brief review of dense granular and their heat transfer properties is introduced, including basic concepts of heat transfer, thermal behavior of these materials, and factors that affect this behavior.
HYDRODYNAMICS OF TRICKLE BED REACTORS Steady- and Nonsteady-State Operations
TL;DR: Aydin et al. as mentioned in this paper investigated the hydrodynamics of TBR at increased temperature and pressure under constant throughput flow and cyclic operation and found that the effect of temperature on fast-mode cyclic operations was negligible.
Journal ArticleDOI
Calibration and uncertainty analysis of a fixed-bed adsorption model for CO2 separation
TL;DR: In this paper, the uncertainty of a one-dimensional fixed-bed adsorption model due to uncertainty in several model inputs, namely, the linear-driving-force (LDF) mass transfer coefficient, axial dispersion, heat transfer coefficients, and adsorbent properties, is analyzed.

A review on experience feedback and numerical modeling of packed-bed thermal energy storage systems
TL;DR: In this article, the authors summarize the key aspects of packed-bed thermal energy storage systems and compare the performance of different types of thermal storage systems, including two-tank molten salt technology and thermal stratification.
Journal ArticleDOI
The Prediction of the Emissivity and Thermal Conductivity of Powder Beds
Samuel Sumin Sih,Joel W. Barlow +1 more
TL;DR: In this article, a simple model for estimating the emissivity of the surface of a powder bed by knowing only the bed porosity and its solid emissivities is presented, and the model is compared with experimental measurements for powder beds of alumina, silicon carbide, and iron.
Journal ArticleDOI
Mass-Transfer Properties of Microbubbles. 1. Experimental Studies
Marshall D. Bredwell,R M Worden +1 more
TL;DR: In this paper, the authors used a laser-diffraction technique to determine the interfacial area per unit gas volume, a.k.a. KL, for a synthesis-gas fermentation.
Journal ArticleDOI
An Integrated Thermal and Mechanical Investigation of Molten-Salt Thermocline Energy Storage
TL;DR: In this paper, a comprehensive model of a dual-medium thermocline tank that includes both the heterogeneous filler region as well as the composite tank wall is formulated, and the model accounts separately for the rock and molten-salt regions in view of their different thermal properties.
