As climate change is exacerbated and existing resources are depleted, the need for sustainable industries becomes ever so important. Aviation is not an exception. Despite the overall carbon dioxide emissions related to the aviation sector accounts for 2%–4% currently, forecasts for air travel indicate an annual growth of 3%–5% and other industries...

The objective of this work is to study the coupling of two efficient optimization techniques, Aerodynamic Shape Optimization (ASO) and Topology Optimization (TO), in 2D airfoils. To achieve such goal two open-source codes, SU2 and Calculix, are employed for ASO and TO, respectively, using the Sequential Least SQuares Programming (SLSQP) and the Bi-...

The performance sensitivity of a low-pressure turbine stator-rotor stage of a commercial jet engine to its blades and hub shapes is analyzed. The derivatives of various metrics, such as isentropic efficiency, total pressure ratio, total pressure loss, and loss coefficient are computed using an adjoint solver capable of handling multi-row analyses....

In the search for cleaner and greener ways to fly, the development of hybrid and fully electric aircraft presents a significant challenge for academics, researchers, development centers and industry. From the conceptual and preliminary design to the development of scaled Remotely Piloted Vehicles (RPV) and even 1:1 scale aircraft, numerous and dive...

When stricter noise limits are enforced to legacy wind turbines already deployed, actions need to be taken. In this paper, we present a solution of retrofitting wind turbine blades with additional outer layer skins that change their aeroacoustic footprint. An optimization design framework produces add-ons shapes that, when attached to blades, reduc...

The currently available computational power and improvements of high-fidelity numerical simulations have lead to an increased use of computational fluid dynamics (CFD) in the analysis of turbomachinery flows, particularly in design environments. The optimization cases often contain up to thousands of design variables and gradient-based (GB) optimiz...

The use of high-fidelity computational fluid dynamics (CFD) tools in turbomachinery design has seen a continuous increase as a result of computational power growth and numerical methods improvement. These tools are often used in optimization environments, where gradient-based optimization algorithms are the most common due to their efficiency. In c...

The use of computational fluid dynamics (CFD) tools in turbomachinery has seen an increase as a result of the exponential growth of computational power, as well as of improvements of the accuracy of numerical simulations. These tools are often used in optimization environments, where gradient-based optimization algorithms are the most common due to...

As a result of the continous growth of Wind Turbines (WTs) implementation worldwide, the problem of WT noise has become more relevant than ever. The increase of noise legal constraints and their non uniformity across different countries and/or regions make it important to address this problem early in the design phase of a WT. However, one might wa...

Power production from wind energy has been increasing over the past decades, with more areas being used as wind farms and larger wind turbines (WTs) being built. With this development, awareness of the impact of wind energy on the environment and on human health has also raised. There has been a large interest in developing fast turnaround WT blade...

Power production from wind energy has been increasing over the past decades, with more areas being used as wind farms and larger wind turbines (WTs) being built. As the awareness of the impact of wind energy on the environment and human health as also increased, so has the interest in developing fast turnaround WT blade design frameworks capable of...
