Turbulence and unemployment in a job matching model [PDF]
According to Ljungqvist and Sargent (1998), high European unemployment since the 1980s can be explained by a rise in economic turbulence, leading to greater numbers of unemployed workers with obsolete skills.

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT The objective of the current research is to characterize the thermal performance in micropolar fluid flows on a vertically elongated porous sheet in the presence of buoyancy forces. Thus, the motivation of this study is to improve the understanding of buoyancy‐driven micropolar fluid flows through porous media, which are relevant to advanced ...

FluidsSymmetry transformation methods are widely used in fluid flow problems. One such method is renormalization group analysis. Renormalization group methods are used to develop a macroscopic turbulence model for non-Newtonian fluids (Oldroyd-B type).

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT Proton exchange membrane fuel cells (PEMFC) are regarded as the best clean energy conversion technology because of their smaller number of emissions and higher efficiency. This numerical investigation used two different flow channel designs—the serpentine flow field (SFF) and the lung serpentine flow field (LSFF)—with active areas of 5 by 5 cm.

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT In the pulverized coal boiler industry, reducing NOx emissions has become a critical objective. Although low‐NOx combustion technologies are effective, they may lead to localized high‐temperature corrosion. To address this issue, near‐wall air supply technology has been introduced, which involves injecting an appropriate amount of air near the

On exact solutions of κ-ε turbulence model
Научный вестник МГТУ ГА, 2016 A method of constructing invariant solutions is applied to turbulence model. Exact solutions for turbulence model are obtained. The method for construction of exact solutions used in this paper may be applied to other models of turbulence.
