Streak formation in flow over biomimetic fish scale arrays

Advancements in Biomimetic Hair Flow-sensor Arrays

In this paper we present the latest developments in the design, fabrication and application of single and arrays of biomimetic hair flow-sensors towards high-resolution air-flow imaging. Redesigning the electrode system of the hair sensor (using SOI wafer technology) has led to improve the detection limit down to 1 mm/s air-flow amplitude using 3 kHz measurement bandwidth. SOI technology facili...

Biomimetic Micromechanical Adaptive Flow-Sensor Arrays

We report current developments in biomimetic flow-sensors based on flow sensitive mechano-sensors of crickets. Crickets have one form of acoustic sensing evolved in the form of mechanoreceptive sensory hairs. These filiform hairs are highly perceptive to low-frequency sound with energy sensitivities close to thermal threshold. In this work we describe hair-sensors fabricated by a combination of...

simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water

abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...

Polymorphism over Nested Regular Arrays: Theory and Implementation in Fish

Simulation and optimization of live fish locomotion in a biomimetic robot fish

This paper presents simplified hydrodynamics model for a biomimetic robot fish based on quantitative morphological and kinematic parameters of crangiform fish. The motion of four Pangasius sanitwongsei with different length and swimming speed were recorded by the digital particle image velocimetry (DPIV) and image processing methods and optimal coefficients of the motion equations and appropria...
