“…The results demonstrated that the actuators can be used as a promising anti-icing tool for aircraft icing mitigation by taking advantage of the thermal effects of plasma actuation, and the induced aerodynamic effect of the actuator has not been discussed in that study. Tian et al 38 showed an effective icing control using a pulsed dielectric barrier discharge plasma actuation with a freestream velocity of 90 m/s, which exhibits high possibility of the real application of SDBD plasma actuation in preventing aircraft icing in flight.…”

Anti-icing performance using the surface dielectric barrier discharge plasma actuator is studied using detailed visualization and surface thermal measurements. To reveal the physical mechanism of coupled aerodynamic and thermal effects on anti-icing, three types of actuators are designed and mounted on a NACA 0012 airfoil. The coupled aerodynamic and thermal effects are confirmed in still air. The results show that the plasma actuation is effective for in-flight anti-icing, and the anti-icing performance is directly related to the design of the plasma actuators based on the coupled aerodynamic and thermal effects. When the direction of plasma induced flow is consistent with the incoming flow, the heat generated by plasma discharge is concentrated in the region of the actuator and the ability of the actuator for heat transfer downstream is relatively weak during the anti-icing. When the induced flow is opposite to the incoming flow, there is less heat accumulation in the actuator region, while the ability of heat transfer downstream becomes stronger. With the consistent and opposite direction of induced flow, the plasma actuation can ensure that 57% and 81% chord of the lower surface of the airfoil are free of the ice accumulation, respectively. Another actuator is designed to induce the air jets approximately perpendicular to the airfoil surface. This exhibits both a stronger ability of heat accumulation locally and heat transfer downstream and hence ensures that there is no ice on the entire lower surface of the airfoil.

“…The effect and efficiency of nSDBD-based de-icing on aircraft wings were confirmed in an early experiment [19] in 2016. Later, the concept of plasma-assisted anti-icing or icing control was proposed [20,21] and a rich set of experiments were conducted [22][23][24][25][26][27][28][29][30][31][32][33][34] in the following years. It was found that at the same total power input, an acSDBD has a better anti-/de-icing performance in comparison to a conventional electrical film heater if a duty-cycle modulation [23,28] is used.…”

The characteristics of nanosecond-pulsed dielectric barrier discharge (nSDBD) in an anti-icing configuration is studied. The mechanisms and energy characteristics of the nSDBD-based plasma-assisted anti-icing are analyzed using a numerical model and existing experimental data. Two-dimensional simulations based on PASSKEy (PArallel Streamer Solver with KinEtics) code are conducted. The code couples a self-consistent fluid model with detailed kinetics, an efficient photo-ionization model, Euler equations and a heat transfer equation for solid materials. The results of icing wind tunnel experiments conducted by two groups are analyzed together. The reduced electric field and the electron density are examined for highvoltage pulses with 800 ns and 20 ns width. The 'merge' of counter-propagating surface streamers with the same polarity is numerically observed under high-voltage amplitude. The effects of gas heating and solid heating in time scales of one pulse and one duty cycle are compared, and the key mechanism for icing prevention is direct fast gas-heating energy transfer from gas to ice/water accumulated on the surface in each duty cycle.

“…Furthermore, electro-thermal systems require in general materials with high thermal conductivity, which is inapplicable to the new generation erosion resistant polymers [58]. Another option for active icing protection is via mechanical vibrations excited through ultrasonic, piezoelectric or dielectric actuators [59][60][61][62]. Despite of consuming less energy, the efficiency of mechanical approach is highly restricted due to insurmountable inherent energy losses in the actuator, reducing the amplitude of mechanical oscillations applied to destroy the ice bonds.…”

The severe environmental conditions in winter seasons and/or cold climate regions cause many inconveniences in our routine daily-life, related to blocked road infrastructure, interrupted overhead telecommunication, internet and high-voltage power lines or cancelled flights due to excessive ice and snow accumulation. With the tremendous and nature-inspired development of physical, chemical and engineering sciences in the last few decades, novel strategies for passively combating the atmospheric and condensation icing have been put forward. The primary objective of this review is to reveal comprehensively the major physical mechanisms regulating the ice accretion on solid surfaces and summarize the most important scientific breakthroughs in the field of functional icephobic coatings. Following this framework, the present article introduces the most relevant concepts used to understand the incipiency of ice nuclei at solid surfaces and the pathways of water freezing, considers the criteria that a given material has to meet in order to be labelled as icephobic and clarifies the modus operandi of superhydrophobic (extremely water-repellent) coatings for passive icing protection. Finally, the limitations of existing superhydrophobic/icephobic materials, various possibilities for their unconventional practical applicability in cryobiology and some novel hybrid anti-icing systems are discussed in detail.
