Effects of inertia on the time-averaged propulsive performance of a pitching and heaving foil
(Elsevier, 2023)The inertia may play an important role in the unsteady behavior of a flapping foil. Of particular relevance in forward flapping locomotion is how the foil inertia may affect its time-averaged propulsive performance. This ... -
Efficient self-propelled locomotion by an elastically supported rigid foil actuated by a torque
(Elsevier, 2022-11-19)A new theoretical model is presented for an aquatic vehicle self-propelled by a rigid foil undergoing pitching oscillations generated by a torque of small amplitude applied at an arbitrary pivot axis at which the foil is ... -
Evolutionary optimization of a motorcycle traction control system based on fuzzy logic.
(IEEE, 2014-11-13)Braking and traction control systems are fundamental vehicle safety equipments. The first ones prevent the wheels from locking, maintaining, when possible, the handling of the vehicle under emergency braking. While the ... -
Experimental characterization of the thermal performance of the Haines 2 solar cooker
(Elsevier, 2022-10-15)This work presents the most exhaustive experimental characterization of the thermal performance of the Haines 2 solar cooker available to date. Two Haines 2 solar cookers were tested side-by-side in Malaga, Spain, 36.7°N, ... -
Experimental determination of the standardised power of a solar funnel cooker for low sun elevations

Experimental thermal performance evaluation of different configurations of Copenhagen solar cooker
(Elsevier, 2021-12-01)In this work, four different configurations of Copenhagen solar cookers were tested experimentally at the same time under the same weather conditions. First tests were carried out using pots without water load. Secondly, ... -
Flutter stability analysis of an elastically supported flexible foil. Application to the energy harvesting of a fully-passive flexible flapping-foil of small amplitude
(Elsevier, 2022-02)The aerodynamic forces on an oscillating flexible foil are used to study the flutter instability when the flexible foil is elastically mounted to translational and torsional springs and dampers at an arbitrary pivot axis. ... -
Force and torque reactions on a pitching flexible aerofoil
(Cambridge, 2023)Experimental measurements in a wind tunnel of the unsteady force and moment that a fluid exerts on flexible flapping aerofoils are not trivial because the forces and moments caused by the aerofoil's inertia and others ... -
Global stability analysis of the natural convection between two horizontal concentric cylinders
(ELSEVIER, 2021-06)In this investigation, the 2D flow between two horizontally positioned concentric cylinders (gravity per- pendicular to the axis of the cylinders), where the inner cylinder is kept at constant temperature Ti higher than ... -
