Description
Предметом изобретени вл етс способ измерени параметров турбулентности пламен и холодных газовых потоков путем введени в них неоднородностей.The subject of the invention is a method for measuring the parameters of the turbulence of flames and cold gas flows by introducing inhomogeneities into them.
Предлагаемь й способ отличаетс от известнь х тем, что распределение вводимых в ма.чосажистые пламена JLTH в холодные газовые потоки иеоднородностен ()отографкруетс с последующим сротометрированием изоб)ажени и определепнем среднеквадратичной составл ющей ггульсаций .The proposed method differs from limestone in that the distribution of JLTH injected into maxillary flames into cold gas streams is heterogeneous () and is then detected with subsequent measurement of isobenia and a definite rms component of gulsiuations.
В бесцветное и-чи малоса/кистое плам через тогкую трубочку ввоДИ1СЯ раствор солн какого-либо щелочного металла (например, соли -чити концентрацией 200 г/л воды), причем трубочка охлаждаетс тем же раствором. При температуре пламени выи1е 1200-1400 в нем образуетс ркий свет щийс конус, который фотографируетс на пластинке панхром с экспозицией 3-4 сек.In the colorless and smallos / cystic flame through a thin tube, a solution of an alkaline metal (for example, a salt with a concentration of 200 g / l of water) is introduced into the solution, and the tube is cooled with the same solution. When the flame temperature is 1200-1400, a bright luminous cone forms in it, which is photographed on a plate with a panchrome with an exposure time of 3-4 seconds.
Профотометрировав пластинку, определ ют распределение почернени вдоль сечени свет щейс струи.By proftometrizing the plate, the blackening distribution along the cross section of the light jet is determined.
Известно, что при малых концентраци х излучающих атомов интенсивность резонансной линии зависитIt is known that at low concentrations of radiating atoms, the intensity of the resonance line depends
от концентрации введенного раствора линейно, при больщих же конп ,ентраци х она пропорциональна корню квадратному из концентрации. Исход з такой зависимости можно из полученного распределени почернений найти распределение концептрацнй , а отсюда при небольщих рассто : х ОТ трубочк (если возмун1ающее вли ние трубочки на утн рассто ни х уже затухло) - интенсивность турбулентности, а на бо.тылкх рассто ни х-коэффициент турбулентной днффузн15. Все определение занимает несколько минут.on the concentration of the injected solution is linear, with large concentrations, it is proportional to the square root of the concentration. The outcome of such a dependence can be obtained from the obtained blackening distribution to find the conceptual distribution, and hence at short distances: x FROM the tubes (if the disturbing influence of the tube on the length of the distances has already died out) - the intensity of turbulence, and on the x-distance distance x-coefficient turbulent diffusion15. The whole definition takes a few minutes.
По данным фотометрировани свет щейс струи и обычного определени фактора контрастности фотопластинки наход т параметры турбулентности пламени в любых интересуюгцих сечени х.According to the photometry of the light jet and the usual determination of the contrast factor of the photoplate, the parameters of flame turbulence are found in any sections of interest.
В хо юдыый газовый поток вместо щелочных солей, свет щихс при высоких температурах, вводитс табач 1ый дым. Холодный поток фотографиругот на репродукционные плаСТИНК15 , фотометрируют их и, определ ют параметры турбулентности ,в 1гнтересуюц,их сечени х. № 106010 Предмет изобретени Спосоо измерени параметров турбулентности пламен и холодных газовых потоков, отличающийс тем, что, с целью получени среднеквадратичной составл ющей пульсации, фотографируют распре- « вводимых в поток неоднородностей с последующим фотометрированием изображени .Instead of alkaline salts, glowing at high temperatures, tobacco 1st smoke is introduced into the cold gas stream. The cold flow of photographic photographs on reproduction plastiNK15, photometric them and, determine the parameters of turbulence, in 1 s, of their cross sections. No. 106010 Subject of the invention is a method for measuring the parameters of the turbulence of flames and cold gas flows, characterized in that, in order to obtain the root-mean-square component of the pulsation, photographic distribution of inhomogeneities introduced into the flow is taken with subsequent photometric measurement of the image.
