Implementation of convective heating in Companhia Siderúrgica Nacional Blast Furnace runners
(2013-01-21)
This paper describes the main characteristics and advantages of convective heating system for refractory lining, compared with conventional heating systems. In addition the main results obtained are presented with its ...
Methodology for DSC calibration in high heating rates
(2011-08-01)
Despite the large use of differential scanning calorimetry (DSC) technique in advanced polymer materials characterization, the new methodology called DSC in high heating rates was developed. The heating rate during ...
Does low-protein diet improve broiler performance under heat stress conditions?
(Fundação APINCO de Ciência e Tecnologia Avícolas, 2004-06-01)
Nutrition for broilers under high temperatures is extremely important for brazilian broiler chicken industry because the amounts of consumed nutrients and environmental temperature have great effects on bird performance ...
An inverse method to estimate the moving heat source in machining process
(PERGAMON-ELSEVIER SCIENCE LTDOXFORD, 2012)
The present work propounds an inverse method to estimate the heat sources in the transient two-dimensional heat conduction problem in a rectangular domain with convective bounders. The non homogeneous partial differential ...
Heating Method Effect on SnO Micro-Disks as NO2 Gas Sensor
(Frontiers Media Sa, 2019-07-16)
There is an increasing concern about NOx emission, and many studies have been carried out using metal oxide semiconductors (MOS) aiming its detection. Among the MOS, the SnO micro-disks present a high sensor response and ...
Respiratory heat loss in the sheep: a comprehensive model
(Springer, 2002-08-01)
A model is presented for the respiratory heat loss in sheep, considering both the sensible heat lost by convection (C-R) and the latent heat eliminated by evaporation (E-R). A practical method is described for the estimation ...
Non-newtonian heat transfer on a plate heat exchanger with generalized configurations
(Wiley-Blackwell, 2007-01-01)
For the configuration optimization of plate heat exchangers (PHEs), the mathematical models for heat transfer and pressure drop must be valid for a wide range of operational conditions of all configurations of the exchanger ...
Two-dimensional axisymmetrical model for a rotating porous wicked heat pipe
(Pergamon-elsevier Science LtdOxfordInglaterra, 1997)
Estudo do calo sensível e latente obtidos por intermédio da razão de Bowen em uma cultura de soja irrigada
(2007-07-01)
The goal of this experiment was to study the latent and sensible heat variation determined by Bowen ratio from an irrigated soybean crop. A micrometeorological station with vertical displacement was constructed to maintain ...
How heat stress (continuous or cyclical) interferes with nutrient digestibility, energy and nitrogen balances and performance in broilers
(2016-10-01)
The effect of continuous and cyclical heat stress on broiler growth performance, nutrient digestibility, energy and nitrogen balances was investigated. Four hundred and fifty, 21-day-old, Cobb male broilers were raised in ...
