Turbulent snow transport and accumulation: New reduced‐order models and diagnostics

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Our new reduced‐order models of snow particle transport provide high‐fidelity calculations of snow accumulation in turbulent flows at significantly reduced computational costs. Additional accumulation diagnostics from the reduced‐order model predict complex patterns of particle concentration in turbulent boundary layers via coherent flow structures in ...

The Productivity Effect of Public–Private Partnership

The Journal of Industrial Economics, EarlyView.
ABSTRACT Public–Private partnerships (PPPs) are often employed by public authorities to deliver infrastructure and public services through contracts bundling construction, operation, and maintenance over extended periods. Using a novel dataset covering the universe of Italian district heating plants (DHs) from 2007 to 2014, I show that PPP improves ...
