Numerical study of the flow past a three-element high-lift airfoil at different angles of attack
(2023)
Conference lecture
Open AccessA parametric study of the 30p30n three-element high-lift airfoil is conducted by changing the angle of attack at α = 5, 9 and 23◦ at a constant Reynolds number of Rec = 750, 000. Computational predictions are performed ... -
Turbulent statistics and coherent structures in an asymmetrically heated channel flow
(2023)
Conference report
Open AccessA compressible direct numerical simulation (DNS) has been conducted to analyze the behavior of a fully developed turbulent channel flow. The problem has been set at mean friction Reynolds number Ret m = 400 submitted to a ... -

(Joint Accelerator Conferences Website (JACoW), 2023)
Conference report
Open AccessIn the field of Particle Accelerators engineering, the design of the cooling channels of its components has been extensively based on experimental correlations for the calculation of convective heat transfer coefficients. ... -
Design and smart control of sensors for optimal performance: a application to wind sensing in Mars
(2019)
Conference report
Open AccessSensor performance in terms of time response and sensitivity can be dramatically enhanced by operating sensors under what may be called a “constant state operation”. This means that any change in the sensor due to external ... -
Active flow control of an aircraft in full stall
(2021)
Conference report
Open AccessThe aerodynamic performance of active flow control on wings using synthetic jets with zero net-mass flow is investigated. The study is conducted via wall-modeled large-eddy simulations using a finiteelement-based solver. ... -
DISCOVERER: Final results and outcomes
(International Astronautical Federation, 2022)
Conference report
Restricted access - publisher's policyThe DISCOVERER project commenced in 2017 with the aim to advance the development of key technologies to enable the commercially viable, sustained operation of satellites in very low Earth orbits (VLEO). Funded by the ... -
Platform and system design study of a VLEO satellite platform using the IRS RF Helicon-based Plasma Thruster
(International Astronautical Federation, 2022)
Conference report
Restricted access - publisher's policyTo achieve a feasible lifetime of several years, most satellites are deployed in orbits higher than 400 km. Drag of residual atmosphere causes a slow orbit decay, resulting in the deorbit of the spacecraft. However, e.g. ... -
Very low Earth orbit constellations for Earth observation
(International Astronautical Federation, 2022)
Conference report
Restricted access - publisher's policyVery Low Earth Orbits (VLEOs), those below 450 km, present a number of benefits and challenges for the development and operation of Earth observation spacecraft at both the system and mission level. This paper examines the ... -
