Estimation of the Biot Number Using Genetic Algorithms: Application for the Drying Process [PDF]
Energies, 2019 The Biot number informs researchers about the controlling mechanisms employed for heat or mass transfer during the considered process. The mass transfer coefficients (and heat transfer coefficients) are usually determined experimentally based on direct ...

Thermal diffusivity and Biot number: A new experimental method
Applied Physics A Solids and Surfaces, 1990 A new simple method is presented for measuring thermal diffusivity and Biot number in cylindrical samples made of relatively highly conducting materials, subjected to laminar air flow. The basic idea is a heat source in the middle section of the sample, acting also as a thermocouple; only one additional temperature sensor at the cylinder basis is ...

Large-Biot-number non-isothermal flow of a thin film on a stationary or rotating cylinder [PDF]
, 2009 Using the lubrication approximation we investigate two-dimensional steady flow of a thin film of fluid with temperature-dependent viscosity on a uniformly heated or cooled horizontal cylinder, which may be stationary or rotating about its axis, in the ...

A universal Biot number determining the susceptibility of ceramics to quenching
EPL (Europhysics Letters), 2009 A universal Biot number of ceramics, which not only determines the susceptibility of the ceramics to quenching but also indicates the duration that the ceramics fail during thermal shock, is theoretically obtained. The present analysis shows that the thermal shock failure of the ceramics with a Biot number greater than this universal value is a very ...

Critical Biot Number of a Periodic Array of Rectangular Fins [PDF]
Journal of Heat Transfer, 2015 We consider the heat transfer problem associated with a periodic array of rectangular fins subjected to convection heat transfer with a uniform heat transfer coefficient. Our analysis differs from the classical approach as (i) we consider two-dimensional (2D) heat conduction and (ii) the wall, to which the fins are attached, is included in the analysis.

Effect of Biot number on the thermocline evolution of a packed bed TES system
Journal of Energy StorageThermal Energy Storage systems are becoming of paramount importance in the context of an efficient and sustainable energy use utilization. These systems are particularly attractive for Concentrated Solar Power plants where the energy surplus is stored as heat and dispatched when solar radiation is insufficient to drive the power block.

Effect of Biot number on the critical condition for spontaneous ignition.
KAGAKU KOGAKU RONBUNSHU, 1987 Thermal behavior of a dust deposit undergoing exothermic reaction can be described by a differential equation, the steady-state solution of which has been proved to exist only when a critical condition is fulfilled. The approximate relationships between criticality and the Biot Number first proposed by Thomas were too complicated for practical use, so ...

Effect of Temperature on the Drying Kinetics of Caturra Coffee: Correlation with Hyperspectral Imaging and Sensory Quality [PDF]
FoodsCoffee processing requires continuous optimization to preserve sensory quality while improving process efficiency. Although hyperspectral imaging has been widely applied for food quality evaluation, its use for predicting coffee cup score during ...

Analysis of Cooling Regimes as a Function of Biot Number During Quenching by Immersion [PDF]
Heat TransferABSTRACT This paper analyses the transition temperature and duration of the cooling regimes (film boiling, transition boiling, nucleate boiling, and convection) during quenching by immersion of specimens covering a range of Biot numbers from 0.70 to 1.32.
