Recently developed an optical laser system should be also an useful method in this field and this one was employed for the present study. Measurements of turbulence by the optical system were carried out first using a small 0. 3 mW laser unit in preliminary experiments and it was shown that a large laser unit is required for the objective measurements. The experiments with a 2 W laser unit were carried out later and the systems feasibility was studied. Through the study, some data of turbulence were obtained for jets from pipes : the movement of small particles for scattering centers in fluids was analyzed : a method to determine the required laser power for the turbulence measurements was obtained : and it was shown that further improvements of the equipments are necessary for the final purpose, measurements of turbulence in gasas flowing from a combustor., 資料番号: NALTM0180000, レポート番号: NAL TM-180}, title = {ジェットエンジン燃焼器出口ガス流の乱れの測定(Ⅱ): レーザのドップラ効果を利用する方法}, year = {1970} }
