1. a supercool big water droplet icing detector, it is characterised in that include the first protruding and rear portion, described first protruding and afterBeing connected by groove between portion, described rear portion is made up of several second projections, is connected by groove between described second projection;

  • This detector uses the method for designing comprised the steps to design;

    (1) one detector configuration of design, this detector configuration includes the first protruding and rear portion, described first is protruding and rear portion itBetween be connected by groove, wherein, described rear portion is made up of several second projections, by groove phase between described second projectionEven;

    (2) Determining The Droplet Trajectories under the detector configuration to step 1 design carries out conventional water droplet calculates, and supercool big water dropletUnder the conditions of Determining The Droplet Trajectories calculate;

    (3) if the result of step 2 shows, under the conditions of conventional water droplet and supercool big water droplet, the first projection and rear portion all there is waterDrip if striking, illustrate that, under the conditions of conventional water droplet and SLD, the first projection and rear portion all can freeze, with regard to None-identifiedSupercool big water droplet condition, raises the height of the first projection or reduces the height of the second projection in rear portion, obtaining new detector structureType, returns the new detector configuration obtained to step 2 and carries out the water droplet under conventional water droplet and under the conditions of supercool big water droplet respectivelyImpact characteristics calculates;

    If under the conditions of conventional water droplet and supercool big water droplet, if rear portion all not having droplets impact arrive, illustrate at conventional water dropletUnder the conditions of SLD, second projection at rear portion is all without freezing, and the also supercool big water droplet condition of None-identified, reduction by first is convexRise height or raise the height of the second projection in rear portion, obtain new detector configuration, the new detector configuration that will obtainReturn step 2 and carry out the Determining The Droplet Trajectories calculating under conventional water droplet and under the conditions of supercool big water droplet respectively;

    If under the conditions of conventional water droplet, water droplet only impinges upon in the first projection of detector configuration, and under the conditions of SLD, firstProtruding all have droplets impact to arrive on rear portion, shows that this detector configuration meets the requirements, and terminates design,.
