Stagnation Temperature Recording [PDF]

open access: yes
The present report deals with the development of a thermometer for recording stagnation temperature in compressible mediums in turbulent flow within 1 to 2 percent error of the adiabatic temperature in the stagnation point, depending upon the speed. This

Smooth leading edge transition in hypersonic flow [PDF]

open access: yes, 1999
The boundary layer transition along the attachment line of a smooth swept circular cylinder in hypersonic flow is investigated in a blowdown wind tunnel. A wide range of spanwise Mach numbers Me (3.28 to 6.78) is covered with the help of different models

Plastics of the Future? Interdisciplinary Review on Biobased and Biodegradable Polymers: Progress in Chemistry, Societal Views, and Environmental Implications

open access: yesAngewandte Chemie International Edition, Accepted Article.
Global demand to reduce polymer waste and microplastics pollution has increased in recent years, prompting further research, development, and wider use of biodegradable and biobased polymers (BBPs). BBPs have emerged as promising alternatives to conventional plastics, with the potential to mitigate the environmental burdens of persistent plastic waste.

Integrating tradition and innovation within a wine tourism and hospitality experience

open access: yesInternational Journal of Tourism Research, Volume 25, Issue 1, Page 169-182, January/February 2023., 2023
Abstract This study explores the strategic choices among wineries involved in wine tourism experiences, including whether they rely on tradition, fully embrace innovation, or combine both. The study, conducted between December of 2018 and January of 2019, draws on face‐to‐face interviews with 32 owners/managers of New World wineries that, on average ...

Influence of thermal stratification and slip conditions on stagnation point flow towards variable thicked Riga plate

open access: yesResults in Physics, 2018
This article addresses thermally stratified stagnation point flow of viscous fluid induced by a non-linear variable thicked Riga plate. Velocity and thermal slip effects are incorporated to disclose the flow analysis.

Influence of Ligand Design and Non‐Covalent Interactions on the Isoselective Ring‐Opening Polymerization of rac‐ß‐Butyrolactone using Salan and Salalen Rare‐Earth Metal Catalysts

open access: yesAngewandte Chemie International Edition, Accepted Article.
We herein report the influence of the ligand framework on the isoselective ring‐opening polymerization (ROP) of rac‐β‐butyrolactone using highly active in situ generated salan [ONNO]H2 and salalen [ONNO]H rare‐earth metal complexes. The stereochemistry was found to be highly dependent on the ortho‐substituents, enabling the synthesis of either ...

Coral reef erosion: In situ measurement on different dead coral substrates on a Caribbean reef

open access: yesLimnology and Oceanography, Volume 67, Issue 12, Page 2734-2749, December 2022., 2022
Abstract Widespread mortality of reef‐building coral substantially reduces the capacity for reef growth and makes available extensive bare substrate areas that in the absence of coral recovery will be eroded by a variety of external and internal bioeroders.

Stagnation point flow of third-grade liquid due to variable thickness: A useful application to non-Fourier heat flux approach

open access: yesResults in Physics, 2018
The impact of modified Fourier’s relation in non-linear mixed convective flow of third grade liquid is examined in this article. Stagnation point flow is considered. Variable thermal conductivity and thermal stratification are examined.

Influence of thermal boundary conditions on heat transfer from a cylinder in cross flow [PDF]

open access: yes
Local heat transfer data over the leading surface of a cylinder in crossflow were obtained for a Reynolds number range of 50,000. The cylinder was operated at both uniform-wall-temperature and uniform-heat-flux thermal ance of 80 deg from the front ...
