| Abstract: | The hot wire anemometer and the ensemble average method are used to measure and study the dispersion turbulent transient feature in a closed cylindrical explosion bomb.The comparison of the dispersion turbulent parameters from different shapes of closed explosion bombs is presented.The relation between errors and numbers in dispersion turbulent measurement with the ensemble average metod is discussed. |
