1. A predictive numerical model of the atmospheric boundary layer based on the turbulent energy equation
Abstract : The atmospheric boundary layer has come into the focus of interest in recent years. Many areas of activity are dependent on accurate information about the boundary layer and prediction of its state. This is true in local weather forecasting, air pollution control and wind energy production. READ MORE

2. Study of adverse-pressure-gradient effects on a flat-plate boundary layer at high Reynolds numbers
Abstract : Turbulent boundary layers are present in many aspects of life, from the weather and wind currents to transportation, production of energy or mixing processes. Understanding turbulent motions can allow for an improvement and development of technical devices, techniques or diagnosis of phenomena where a fluid flow is in the turbulent regime. READ MORE

3. Ionic liquids : The solid-liquid interface and surface forces
Abstract : Ionic liquids (ILs) present new approaches for controlling interactions at the solid-liquid interface. ILs are defined as liquids consisting of bulky and asymmetric ions, with a melting point below 373 K. Owing to their amphiphilic character they are powerful solvents but also possess other interesting properties. READ MORE

4. Experimental study on turbulent boundary-layer flows with wall transpiration
Abstract : Wall transpiration, in the form of wall-normal suction or blowing through a permeable wall, is a relatively simple and effective technique to control the behaviour of a boundary layer. For its potential applications for laminar-turbulent transition and separation delay (suction) or for turbulent drag reduction and thermal protection (blowing), wall transpiration has over the past decades been the topic of a significant amount of studies.

5. Boundary Layer Parametrization in Numerical Weather Prediction Models
Abstract : Numerical weather prediction (NWP) and climate models have shown to have a challenge to correctly simulate stable boundary layers and diurnal cycles. This aim of this study is to evaluate, describe and give suggestions for improvements of the descriptions of stable boundary layers in operational NWP models. Two papers are included. READ MORE
