A Study of Latent Heat of Vaporization in Aqueous Nanofluids

thermal and radiative properties. Such work has generated great controversy, although it is arguably accepted today that the presence of nanoparticles rarely leads to useful enhancements in either thermal conductivity or convective heat transfer. On the other hand, there are still examples of unanticipated enhancements to some properties, such as the reported specific heat of molten salt-based ...

An Equation for the Latent Heat of Vaporization

B = dimensionless coefficient in polynominals b = dimensionless coefficient in polynominals F = dimensionless radial velocity G = dimensionless tangential velocity H = dimensionless axial velocity K = 7 / 2 p r ~ ( v u ) ' / ~ , dimensionless parameter Q = $ow rate 8' = dimensionless flow rate r = radial coordinate u = radial velocity II = tangential velocity w = axial velocity z = axial coordi...

On the Determination of Specific Heat and of Latent Heat of Vaporization with the Vapor Calorimeter

The Latent Heat of Vaporization of a Widely Diverse Class of Fluids

externally incident radiation. The present study provides a simple, straightforward, and highly accurate method of analysis for the determination of angular distribution of radiation anywhere in the medium. As an independent check, the results are compared with those calculated with the FN method [4]; the agreement was very good. Computations require very little computer time. In the tables pre...

A definitive heat of vaporization of silicon through benchmark ab initio calculations on SiF4

In order to resolve a significant uncertainty in the heat of vaporization of silicon — a fundamental parameter in gas-phase thermochemistry — ∆H◦ f,0[Si(g)] has been determined from a thermochemical cycle involving the precisely known experimental heats of formation of SiF4(g) and F(g) and a benchmark calculation of the total atomization energy (TAE0) of SiF4 using coupled-cluster methods.
