Such full-domain RBF methods are highly flexible and can exhibit spectral convergence rates Madych & Nelson (1990). However, in their traditional implementation the fully-populated matrix systems which are produced lead to computational complexities of at least order- N 2

Delayed-mix burners are a special form of nozzle mix, in which mixing is intentionally slow. (A raw gas torch is an unintentional form of delayed mixing.) Ignition of a fuel with a shortage of air results in polymerization or thermal cracking that forms soot particles onl[r]

3. Numerical analysis
A numerical analysis of thermo-fluid dynamics characteristics is conducted by adopting the SIMPLER algorithm developed by Patankar (1980). While the convection term is discretised using the QUICK finite-difference scheme (Thakur & Shyy, 1993), the central[r]

It has been observed by various investigators that the suspension of nanoparticles in base fluids show anoma- lous enhancements in various thermophysical properties, which become increasingly helpful in making their use as cooling fluids more effective [1-4]. While the reasons for the anomalo[r]
