Electrostatic Levitation Technique for Thermo- Physical Property Measurements of Molten Materials on Earth and in Space
Themophysical properties of high temperature molten materials are mczsured using an electrostatic levitator in combination with several diagnostic devices. An objective of this study is to find the limitation of the earth-based measurements in order to evaluate the necessity of similar measurements in space. It is found that the hemispherical total emissivity, specific heat, specific volume, de...
متن کاملMinimizing convection effects to measure diffusion in liquid droplets during high-temperature electrostatic levitation
We present an approach to reduce the convective flow in an electrostatically levitated liquid droplet to such an extent that diffusion is the dominant mechanism for mass transport, thus enabling direct measurements of atomic diffusion in reactive liquids at elevated temperatures. Convection is minimized by containerless processing, and reducing temperature variations in the sample. The diffusio...
متن کاملbuckling of viscoelastic composite plates using the finite strip method
در سال های اخیر، تقاضای استفاده از تئوری خطی ویسکوالاستیسیته بیشتر شده است. با افزایش استفاده از کامپوزیت های پیشرفته در صنایع هوایی و همچنین استفاده روزافزون از مواد پلیمری، اهمیت روش های دقیق طراحی و تحلیل چنین ساختارهایی بیشتر شده است. این مواد جدید از خودشان رفتارهای مکانیکی ارائه می دهند که با تئوری های الاستیسیته و ویسکوزیته، نمی توان آن ها را توصیف کرد. این مواد، خواص ویسکوالاستیک دارند....
Pure and Pseudo-pure Fluid Thermophysical Property Evaluation and the Open-Source Thermophysical Property Library CoolProp
Over the last few decades, researchers have developed a number of empirical and theoretical models for the correlation and prediction of the thermophysical properties of pure fluids and mixtures treated as pseudo-pure fluids. In this paper, a survey of all the state-of-the-art formulations of thermophysical properties is presented. The most-accurate thermodynamic properties are obtained from mu...
متن کاملReal-Time Measurements of Temperature and Velocity Profiles of Polymer Melts using Application Visualization System
Polymer melts are highly-viscous non-Newtonian fluids. The manufacture of an article from polymer involves heating, shaping and cooling processes. The rheology of the polymer melt is considered to be one of the most important factors in determining the properties of a polymer product, the properties being related to the flow and deformation of the fluid particles in the processing equipment. Th...
