The German Aerospace Center designed, aero-mechanically optimized and experimentally investigated its own counter-rotating shrouded fan stage in the frame of the project CRISPmulti. Their target and the motivation of this work was, on the one hand, t

Due to the increasing bypass ratios of modern engines, the fan stage is increasingly becoming the dominant source of engine noise. Accordingly, it is becoming more and more important to develop not only efficient but also quiet fan stages. In this pa

Achieving higher efficiency and less weight is the most important target for future engine development. New lightweight materials like fiber reinforced composites should be applied for the fan blading to reduce the weight. The aerodynamic efficiency

New aircraft concepts such as boundary layer ingestion (BLI) are essential to achieve a reduction of engine emissions and aircraft noise. The key-point of this concept is that the engine ingests and reaccelerate the boundary layer from the aircraft f

Deflections at off-design conditions can change the aeroelastic behavior of turbomachinery blades significantly. Therefore, steady-state deformations at each operating point cannot be neglected and need to be captured by CFD-CSM coupling. The impleme

A promoter polymorphism in the serotonin transporter gene (5-HTTLPR) has been reported to confer relative risk for phenotypes (depression/anxiety) and endophenotypes (amygdala reactivity). In this report, we identify and characterize three rare 5-HTT

On possible fan concept for future high and ultra-high bypass ratio turbofan engines is the counter-rotating (CR) fan. Several studies [1][2][3][4] dealt already with the optimization of CR fans, however the mass flow and the total pressure ratio wer

The focus of the present study is to assess and quantify the uncertainty in predicting the steady and unsteady aerodynamic performance as well as the major mechanical characteristics of a contrarotating turbofan, primarily due to geometric variations

The effect of hydrophilic linear polymer additives (non-cross-linked polyacrylamide, hydroxyethyl cellulose and polyethylene oxide) on the migration behavior of double stranded DNA molecules, ranging from 200-1000 base pairs, were studied in ultra-th

Electroosmotic properties of agarose gels with low, medium, high and super high electroendosmosis (EEO) were evaluated based on the apparent electric field mediated mobility of a neutral, fluorescent marker under constant field strength using ultrath
