Burner Backflow Reduction in Regeneration Furnace

Evaluating Heat Flux Profiles in Aluminum Reheating Furnace with Regenerative Burner

Abstract: Properly understanding heat flux characteristics is a crucial prerequisite to efficiently applying a regenerative burner in an aluminum reheating furnace. A series of experiments was conducted in this study in order to establish a database of the best available burners according to furnace temperature, excess air ratio, and flame combustion mode as they affect heat flux characteristic...

Backflow and Density Excitations in Quantum Fluids

By the use of the f sum rule and a separation of density excitations into single and multiple excitations, we derive exact quantum expressions for the ~ backflow contribution to the dynamic structure function S(k, co) and for the discrete single-excitation spectrum ok:. The derivation is carried out for Bose liquids, Fermi liquids, charged quantum liquids, quantum solutions, an impurity atom di...

The Quantum Backflow Effect

The quantum phenomenon of probability backflow is explored. This remarkable effect arises when considering the motion of a free particle in one dimension. For a state consisting only of positive momenta, it is possible for probability to flow in the opposite direction to the particle’s momentum. A comprehensive review of the literature and some new material is presented on the backflow effect, ...

Backflow in Post-asymptotic Giant Branch Stars

We derive the conditions for a backflow toward the central star(s) of circumstellar material to occur during the post-asymptotic giant branch (AGB) phase. The backflowing material may be accreted by the post-AGB star and/or its companion, if such exists. Such a backflow may play a significant role in shaping the descendant planetary nebula, by, among other things, slowing down the post-AGB evol...
