Steady-state and time-dependent heat fluxes through building envelope walls: A quantitative analysis to determine their relative significance all year round
(Elsevier, 2020-05)
The selection of the best type of building envelope wall for a given location and the calculation of the heat flux exchanged with the exterior environment are key issues in avoiding undesirable heat losses and gains, thus ...
Experimental Determination of Surface Heat Transfer Coefficient in a Dry Ice-ethanol Cooling Bath Using a Numerical Approach
(Cryo Letters, 2017-03)
Dry ice-ethanol bath (-78ºC) have been widely used in low temperature biological research to attain rapid cooling of samples below freezing temperature. The prediction of cooling rates of biological samples immersed in dry ...
Contribution to dynamic characteristics of the cutting temperature in the drilling process considering one dimension heat flow
(PERGAMON-ELSEVIER SCIENCE LTD, 2011)
The machining of hardened steels has always been a great challenge in metal cutting, particularly for drilling operations. Generally, drilling is the machining process that is most difficult to cool due to the tool`s ...
Optimization-based design of a heat flux concentrator
(Nature Publishing Group, 2017-01)
To gain control over the diffusive heat flux in a given domain, one needs to engineer a thermal metamaterial with a specific distribution of the generally anisotropic thermal conductivity throughout the domain. Until now, ...
Effective parameters for conductive contributions to radial heat transfer in fixed beds under stagnant conditions
(Inst Chemical Engineers, 2017-03)
New expressions to evaluate the thermal conduction parameters in fixed beds of monosized spheres are presented in this paper. The parameters are those introduced by the 2R2D model proposed by Asensio et al. (2014): the ...
A two phase flow nonlinear parameter estimation for capillary tube-suction line heat exchanger
(2001-12-01)
Here we present two-phase flow nonlinear parameter estimation for HFC's flow through capillary tube-suction line heat exchangers, commonly used as expansion devices in small refrigeration systems. The simplifying assumptions ...

Thermal balance of Nellore cattle
(Springer, 2018-05-01)
This work aimed at characterizing the thermal balance of Nellore cattle from the system of indirect calorimetry using a facial mask. The study was conducted at the Animal Biometeorology Laboratory of the So Paulo State ...
A model of heat transfer through feather layers of broiler chicks - An operation with a heat source
(2014-01-01)
Broilers acquire thermoregulatory maturity at approximately ten days post-hatching and undergo physiological changes during the rearing period. During this process, the birds have high sensitivity to low air temperatures ...
