Computational fluid dynamics simulations of airflow through the nasal passages of rhinolophoid bats
The Anatomical Record, EarlyView.Abstract The nasal passages of bats that emit their echolocation call through their nostrils have adapted for sound emission as well as standard respiratory and olfactory functions. Rhinolophids, hipposiderids and rhinonycterids all use a high duty cycle (HDC) echolocation strategy.

Secondary flow reduction techniques in linear turbine cascades [PDF]
, 1993 This thesis investigates a novel secondary flow reduction method. The inlet boundary layer to a linear turbine cascade is skewed by injection of air through an upstream slot to oppose regular generated negative stream wise vorticity.

TurboFlow: Meanline Modelling of Axial Turbines
Journal of Open Source SoftwareMeanline modeling is a fundamental approach used in the design and analysis of axial turbines (Dixon, 2014). The method simplifies the analysis by assuming a uniform flow and incorporates semi-empirical correlations to estimate performance. This approach allows for a reasonably accurate approximation at low computational cost.TurboFlow is a Python ...

Biofuels, Bioproducts and Biorefining, EarlyView.Abstract This study investigates the relationship between artificial intelligence (AI) development and biofuel production using a balanced panel dataset of 12 European Union (EU) countries over the 2008–2024 period. Employing feasible generalized least squares (FGLS) estimation with distributed lag specifications, the analysis controls for Renewable ...

Simulating wind turbine interactions using the vorticity transport equations
, 2009 The aerodynamic interactions that can occur within a wind farm result in the constituent turbines generating a lower power output than would be possible if each of the turbines were operated in isolation.

The effect of upstream duct boundary layer growth and compressor blade lean angle variation on an axial compressor performance [PDF]
, 2010 The compressor of a gas turbine engine is extremely vulnerable on upstream duct- induced flow non-uniformities whether the duct is an engine intake or an interconnecting duct.

Modeling of Turbine Engine Axial-Flow Compressor and Turbine Characteristics
Journal of Propulsion and Power, 2000 The paper describes the concept of modeling the turbine engine axial-flow compressor and turbine characteristics by using the function of two variables. Accuracy of the proposed concept has been verified on the example of the given compressor and turbine characteristics.

A Method for Optical Quantification of Local Oxygen Limitations in Multiphase Bioreactors
Biotechnology and Bioengineering, EarlyView.ABSTRACT Spatial oxygen limitation is a major source of physiological stress and metabolic, scale‐dependent heterogeneity in aerobic bioprocesses. In gas‐liquid stirred tank reactors, oxygen availability is governed by hydrodynamics and mass transfer and is therefore inherently non‐uniform.
