The accuracy of differential scanning calorimetry (DSC) used in the dynamic method, which is method most widely to measure thermal performance existing phase-change materials (PCMs), limited when measuring range and peak temperature PCMs combined with building materials. Therefore, we measured a thermochamber; samples were sheet shape-stabilized material (SSPCM) microencapsulated PCM-impregnate...

Measurement of the phenomena associated with hypervelocity boundary layer transition requires the development of high-speed detection techniques. Two reasons for the current search for a reliable non-intrusive optical technique include: 1) high-enthalpy facilities suffer from a harsh environment in the test section after the test time, 2) optical diagnostics tend to achieve higher sampling rate...

A vortex particle method for the simulation of twodimensional compressible flows is developed. The computational elements are Lagrangian particles that carry vorticity, dilatation, enthalpy, entropy and density. The velocity field is decomposed into irrotational and solenoidal parts, which allows its calculation in terms of the particles’ vorticity and dilatation. The particle coverage is trunc...

Isothermal titration calorimetry (ITC) is a straightforward method to determine basic chemical details of a binding interaction (affinity, thermodynamics and stoichiometry) in a single experiment and under native conditions [1, 2]. Traditionally, ITC experiments are performed using the method of incremental titration, whereby a precise volume of titrant is added to a solution of titrand at disc...

Abstract: In this paper, a new solution of solidification problems in continuous casting based on meshless method is presented with multiple strategies to solve the practical problems. An additional term is added to stabilise the computation with Neumann boundary. The enthalpy method is used to calculate the latent heat and the corresponding iterative solution is given. An iteration scheme for ...

A test substance with characteristics and properties similar to those of cellulose· based solid waste products is needed to calibrate calorimeters and combustors which will be routinely burning these materials to determine their calorific values precisely for use in commerce. Microcrystalline cellulose was found to be a good calibrant for this purpose. The enthalpy of combustion of microcrystal...

The phenomenon of entropy-enthalpy (S-H) compensation is widely invoked as an explanatory principle in thermodynamic analyses of proteins, ligands, and nucleic acids. It has been suggested that this compensation is an intrinsic property of either complex, fluctuating, or aqueous systems. The questions examined here are whether the observed compensation is extra-thermodynamic (i.e., reflects any...
