CFD‐Based and Control‐Oriented Modeling of a Counterflow Heat Exchanger With Utilization of Parameter Identification

open access: yesProceedings in Applied Mathematics and Mechanics, Volume 26, Issue 2, June 2026.
ABSTRACT Counterflow heat exchangers (CHXs) thermally couple consumers and producers to a district heating network (DHN). Fluctuating loads and control actions naturally lead to unsteady operation conditions of the network and its components, posing a challenge for DHN models and CHX parameterizations based on Nusselt correlations that assume steady ...

New terrace‐tile inlet technologies reduce sediment and nutrient losses

open access: yesSoil Science Society of America Journal, Volume 90, Issue 3, May/June 2026.
Abstract Surface inlets such as Hickenbottom risers (HBRs) are often used to drain closed depressions and potholes across agricultural landscapes in the US Midwest. Although HBRs provide efficient drainage, they also transport substantial nutrient and sediment losses from fields.
