Feb 02, 2019 · Accurate numerical calculation of the thermal profile in humans requires reliable estimates of the following five tissue properties:specific heat capacity (c), thermal conductivity (k), blood perfusion rates (m), metabolic heat production (A 0), and density (). A sixth property, water content (w, as a %), can also be used to estimate c and k. Cryogenic Material Properties Database (2001)property information for materials used in cryogenics. The initial phase of this program has focused on picking simple models to use for thermal conductivity, thermal expansion, and specific heat. We have broken down the temperature scale into four ranges:a) less than 4 K, b) 4 K to77 K, c) 77 K to 300 K, and d) 300 K to the melting point.
This database is a critical evaluation of existing experimental measurements on the properties of engineering materials at cryogenic temperatures (including room temperature and above). Equations are given for the recommended property value as a function of temperature. Click on the Material Properties link to enter this database. These correlations were developed as part of a past NIST Standard DATABASE » IT'IS FoundationTables are available for the densities, heat capacities, thermal conductivities, heat transfer rates, heat generation rates, viscosities, acoustic properties (speed of sound, attenuation constant, and non linearity), tissue weight fractions, and for MR parameters (longitudinal and transversal relaxation times). Elastic and Thermal Properties Database43 different properties are available:elastic modulus, thermal expansion, thermal conductivity, density, specific heat, electrical resistivity, emissivity, tensile and yield strengths, S-N & -N fatigue curves, true stress-true strain curves, stress-rupture, creep strength, permeability, magnetization and more.
