“…Figure 3 presents time-averaged experimental results of film velocity and thickness plotted along the vertical axis, compared with analytical results in the horizontal axis derived from Eqs. (5) (6). The analytical results of normalized mean velocity and film thickness under variation of gas velocity are well equivalent with the corresponding experimental Fig.…”

“…of a thin liquid film extending on a wall exposed to a fast gas flow is a general thermo-fluid issue in many practical situations, such as film-cooling technology [1][2][3], icing on aircraft wings [4][5][6], and drying of paints and cleaning solutions [7]. Past and recent studies including quantitative measurements [5,[8][9][10][11][12][13][14][15] provide a scenario that the turbulent gas flows over the initially smooth film, soon drives the film with complex wavy structures by Kelvin-Helmholtz (KH) instability as a roll wave, accelerates the wave crests producing transverse wave by Rayleigh-Taylor (RT) instability as a ripple wave, stretches ligaments, and eventually entrains droplets disintegrated by Plateau-Rayleigh instability, all in a sequential fashion.…”

“…The icing of aircraft and wind turbines causes component damage, results in operation disruption, and inherent equipment loss, as well as their potential for causing serious accidents [1,2]. Different types of anti/de-icing methods, such as thermal [3], mechanical [4], chemical [5] and other methods with new principles guide (for example, plasma [6]) have been introduced by researchers to deal with the ice threat. With high reliability and efficiency, ice-protection systems are commonly used on aviation equipment with thermology methods [3].…”

Due to the safety threats caused by icing, the de-icing system is essential in the aviation industry. As an effective method, the electromechanical de-icing system (EDS) is a new ice-protection system based on mechanical vibration principles. For the majority of the current research on system de-icing capability estimation, the effect of impedance-matching is not considered. Impedance matching plays a very important role in improving the performance of the electromechanical system, so we must also consider the impact of impedance matching when designing the EDS. In the present study, a de-icing capability prediction method considering the impact of an impedance-matching device is established based on experimental and numerical methods. The results indicate that the impedance-matching effect has no impact on the mechanical vibration of the structure for the same load power. Meanwhile, impedance-matching devices can significantly improve the power factor and increase the interface shear stress/strain for de-icing. Eight different vibrational modes were tested, and the experimental results showed that the actual interface shear strain after impedance matching is inversely proportional to the de-icing time. The verification experiments were conducted and the accuracy of the proposed prediction method was verified.

“…They concluded that the hole diameter on the piccolo tube was one of the critical structural parameters. In addition to optimizing thermal icing mitigation for the wing, a similar trend can be seen to optimize the mitigation of icing on the engine inlet guide vane [117][118][119][120].…”

A Review on the Current Status of Icing Physics and Mitigation in Aviation

2021

View full text Add to dashboard Cite

Icing on an aircraft is the cause of numerous adverse effects on aerodynamic performance. Although the issue was recognized in the 1920s, the icing problem is still an area of ongoing research due to the complexity of the icing phenomena. This review article aims to summarize current research on aircraft icing in two fundamental topics: icing physics and icing mitigation techniques. The icing physics focuses on fixed wings, rotors, and engines severely impacted by icing. The study of engine icing has recently become focused on ice-crystal icing. Icing mitigation techniques reviewed are based on active, passive, and hybrid methods. The active mitigation techniques include those based on thermal and mechanical methods, which are currently in use on aircraft. The passive mitigation techniques discussed are based on current ongoing studies in chemical coatings. The hybrid mitigation technique is reviewed as a combination of the thermal method (active) and chemical coating (passive) to lower energy consumption.
