Combustion Characteristics of RDF.

KAGAKU KOGAKU RONBUNSHU, 1996
都市ごみからつくられた RDF (ごみ固形化燃料) を対象とした循環流動層燃焼による高効率発電プロセスを開発するための基礎データとして, 製造方法の異なる 2 種類の RDFの燃焼特性について高温型示差熱天秤を用いて検討した.これらの RDF は燃焼時において発熱を伴う 2 段階の重量減少がみられる. このことからこれらの RDF は低温域で燃焼する成分と高温域で燃焼する成分の 2 成分からなることが示された. また燃焼後と熱分解後の試料の重量差がほとんどないことから, これらの燃焼が主に試料の熱分解によって放出される揮発分の気相燃焼であることがわかった.

Characteristic phenomena in combustion [PDF]

Discrete Dynamics in Nature and Society, 1997
For the case of a reaction–diffusion system, the stationary states may be represented by means of a state surface in a finite‐dimensional state space. In the simplest example of a single semi‐linear model equation given. in terms of a Fredholm operator, and under the assumption of a centre of symmetry, the state space is spanned by a single state ...

Numerical Investigation of the Effect of Sudden Expansion Ratio of Solid Fuel Ramjet Combustor with Swirling Turbulent Reacting Flow

Energies, 2019
In this paper, the effect of sudden expansion ratio of solid fuel ramjet (SFRJ) combustor is numerically investigated with swirl flow. A computational fluid dynamics (CFD) code is written in FORTRAN to simulate the combustion and flow patterns in the ...

Recycling of NiTi Shape Memory Alloys: Fundamental and Technological Aspects of a Vacuum Induction Melting Processing Route

Advanced Engineering Materials, EarlyView.
The present study investigates recycling of NiTi shape memory alloys via vacuum induction melting. An ingot was synthesized from elemental Ni and Ti and subjected to three subsequent remelting cycles. Remelting increases process durations and impurity levels and adversely affects microstructures and functional properties.

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying

Advanced Engineering Materials, EarlyView.
An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.
