Thermal diffusivity of porous cordierite ceramic burners

Effects of Matrix Cracks on the Thermal Diffusivity of a Fiber-Reinforced Ceramic Composite

Effects of matrix cracks and the attendant interface debonding and sliding on both the longitudinal and the transverse thermal diffusivities of a unidirectional Nicalon/MAS composite are investigated. The diffusivity measurements are made in situ during tensile testing using a phase-sensitive photothermal technique. The contribution to the longitudinal thermal resistance from each of the cracks...

investigation on improvement of radial porous burners in comparison to conventional porous burners

in studies done on porous burner, generally burners with axial flow are considered. in this paper, porous burners with radial and axial flow have been modeled numerically and results of radial and axial porous burners with equal fuel consumptions are compared. the mechanism used in combustion phenomenon is 15 stage mechanisms which predict the pollutions production precisely. the results show a...

NON-DESTRUCTIVE THERMAL DAMAGE CHARACTERIZATION OF CORDIERITE-MULLITE REFRACTORIES

Abstract: Refractory materials containing cordierite (2MgO.2Al2O3.5SiO2) and mullite (3Al2O3.2SiO2) are used as support in furnaces, because of their low thermal expansion properties which confer them a very good ability to thermal shock resistance. Composed of two phases presenting very different CTE (1.5–3×10-6 for cordierite and 4–6×10-6 K-1 for mullite), these materials can develop damag...

Thermal Design of Gas-Fired Cooktop Burners Through ANN

INTRODUCTION Recent advances in the applications of ANN have demonstrated successful cases in time series analysis, data mining, civil engineering, financial analysis, music creation, fishing prediction, production scheduling, intruder detection, etc., making them an important tool for research and development[1]. ANN and evolutionary computation(EC) techniques have been employed successfully i...
