Experimental propane/air Bunsen flame at atmospheric pressure are investigated in the context of DarrieusLandau (DL) instability. Results from asymptotic theory are utilized in order to estimate the non-dimensional critical length scale δc = LD/λc (LD the flame thickness and λc the critical length scale). The non-dimensional flame thickness δ = LD/L is varied either by varying the equivalence r...

We describe an inexpensive and convenient container that solves some common problems associated with storing microcentrifuge tubes in refrigerators and freezers. It is made from a plastic box that comes prepackaged with pipet tips, and we have used FISHERbrand Redi-Tip boxes Catalog No. 21-197-8H (size 200 μL) or Catalog No. 21-197-2E (size 0.5–10 μL) (Fisher Scientific, Pittsburgh, PA, USA) w...

and approaching its definitive links with genetic studies, especially through studies of bacteriophage. The famous "green paper" by Timofeeff-Ressovsky, Zimmer and Delbruck was published in 1933; Schlesinger pointed to the resemblance in chemical composition of phage and of chromosomes, carriers of genetic information, three years later; the Wollmans in Paris made pioneering contributions to th...

Combustion of hydrocarbons with pure oxygen as oxidizer is used, e.g., in high-temperature processes such the partial oxidation (POX) to produce synthesis gas high purity. Due prevailing temperatures, active cooling required for many parts. For laboratory-scale experiments, dimensions key parts are too small conventional manufacturing processes. One example a burner plate especially developed P...

Since a large number of physical parameters influence the flame dynamics in a full scale gas turbine combustor, it is virtually impossible to develop physically correlated reduced order models for flame dynamics by directly studying these complex reacting flows. Even the Rijke tube combustor system, though comprising of a simple geometry and a flat flame, shows a strong nonlinear coupling betwe...
