THE MONUMENT TO ROBERT BUNSEN

Monument to the discoveries.

A week ago I was standing with my wife by the River Tagus in Lisbon, next to the Monument to the Discoveries. The monument is at the spot where Vasco da Gama set out to discover the southeast passage from Europe to Asia, past the Cape of Good Hope. Vasco’s discovery marked the beginning of the Portuguese maritime empire. At the furthest tip of Europe, Portugal was perfectly situated to found su...

Infrared radiation from a Bunsen flame.

Many observers have studied th e infrared emi sion of a Bunsen flame [11. 2 The strongest band ocem s at about 4.4 Il and is produced by carbon dioxid e. Other bands have been found a t 0.95, 1.45, 2.0, and 2.8 Il , and are a ttributed to carbon dioxide and water vapor. Very little radiation has been observed in the region beyond 7 Il . In the visible and ultraviolet regions of the spectrum, co...

Investigation of Bunsen flame dynamics by the method of characteristics

Understanding the dynamics and the stabilisation of flames is important for practical applications and for theoretical research. Here, to investigate the time-evolution of a Bunsen flame in a Poiseuille flow, we extend a G-equation-based kinematic model by accounting for flame stabilisation. The nonlinear G-equation is solved analytically using the methods of characteristics. The solution is th...
