Channel-to-channel heat flux variation in compact minichannel heat exchangers due to the effect of louvered fins

A typical minichannel evaporator used in AC&R applications is made of stacked parallel aluminum extruded multiport plates and louvered fins placed between them. In this configuration cold refrigerant flows inside the ports, and hot air passes though the lo ...

Real-Time Control of an Ensemble of Heterogeneous Resources

Jean-Yves Le Boudec, Andrey Bernstein, Niek Johannes Bouman

This paper focuses on the problem of controlling an ensemble of heterogeneous resources connected to an elec- trical grid at the same point of common coupling (PCC). The controller receives an aggregate power setpoint for the ensemble in real time and trac ...

Impact of Extreme Land Surface Heterogeneity on Micrometeorology over Spring Snow Cover

Michael Lehning, Sebastian Schlögl

The melting mountain snow cover in spring typically changes from a continuous snow cover to a mosaic of patches of snow and bare ground, inducing an extreme heterogeneity of the land surface. A comprehensive measurement campaign, the Dischma experiment, wa ...

Estimating Non-Conductive Heat Flow Leading to Intra-Permafrost Talik Formation at the Ritigraben Rock Glacier (Western Swiss Alps)

Michael Lehning

Although non-conductive heat flow plays an important role in the evolution of rock glacier temperature and dynamics, few studies have quantified it. At the Ritigraben rock glacier (Switzerland), intra-permafrost talik formation was observed at around 12m d ...

Studies of Two-Phase Flow at a Chute Aerator with Experiments and CFD Modelling

Michael Pfister

The chute aerator of a spillway is a structure in such a sense that air is, in the intense emulsification, entrained into the high-velocity water flow. Correctly predicting the air entrainment and two-phase flow pattern at the aerator would contribute to r ...

Unsteady Aerodynamics of Low-Pressure Steam Turbines Operating Under Low Volume Flow

Peter Ott, Benjamin Megerle, Ivan William McBean

Nonsynchronous excitation under low volume operation is a major risk to the mechanical integrity of last stage moving blades (LSMBs) in low-pressure (LP) steam turbines. These vibrations are often induced by a rotating aerodynamic instability similar to ro ...
