Moisture dependent thermal properties of selected vegetables in Akwa Ibom State, Nigeria

Research in Agricultural Engineering, 2019
The thermal properties of some selected vegetables in Akwa Ibom State, Nigeria were investigated. The specific heat, thermal conductivity and thermal diffusivity for the five selected vegetables (Afang, Nkong, Atama, Editan and Nton) were determined and ...

Thermal properties of fluoride mixtures near the melting point

Chimica Techno Acta
The thermal diffusivity of LiF-NaF-KF (FLiNaK), NaF-KF and FliNaK-NdF3 mixtures was studied by laser flash method near the melting point. The obtained results demonstrate that the thermal diffusivity of the melts slowly decreases within a certain ...

Thermal Diffusion of a Two Layer System

, 1995
In this paper thermal conductivity and thermal diffusivity of a two layer system is examined from the theoretical point of view. We use the one dimensional heat diffusion equation with the appropriate solution in each layer and boundary conditions at the

Validation of data analysis routines for a thermal probe apparatus using numerical data sets [PDF]

, 2008
Most thermal properties of construction materials used in the analysis of building performance have been measured under laboratory conditions, using a guarded hot box or hot plate apparatus. As a consequence, these properties seldom reflect the impact of

Low-frequency heat waves transport in graded Si–Ge alloys

AIP Advances, 2023
In this work, we consider a rigid heat conductor graded material subjected to an oscillating thermal signal applied on its boundary. We use a recently proposed novel concept, the so-called spectral diffusivity, to characterize the response of the ...

Mean Temperature Profiles in Turbulent Thermal Convection

, 2017
To predict the mean temperature profiles in turbulent thermal convection, the thermal boundary layer (BL) equation including the effects of fluctuations has to be solved. In Shishkina et al., Phys. Rev. Lett.
