    • Gas hold-up profiles measurement using ultrasonic sensor 

      Mohd Hafiz, Fazalul Rahiman; Ruzairi, Abdul Rahim, Prof. Dr.; Herlina, Abdul Rahim, Dr. (Institute of Electrical and Electronics Engineers (IEEE), 2011-02)
      In this letter, we present a work carried out to measure gas hold-up profiles in a liquid column using a pair of ultrasonic sensors. The gas hold-up profiles from 1.85 to 7.7 mm in diameter are of interest in this ...

    • Modelling ultrasonic sensor for gas bubble profiles characterization of chemical column 

      Mohd Hafiz, Fazalul Rahiman, Dr.; Ruzairi, Abdul Rahim, Prof. Dr. ; Herlina, Abdul Rahim, Dr.; Nor Muzakkir, Nor Ayob; Elmy Johana, Mohamad, Dr.; Zulkarnay, Zakaria (Elsevier B.V., 2013)
      In this paper, we present a modelling and experimental work to characterize gas bubble profiles in chemical column using a pair of ultrasonic sensor. The gas bubble profiles from 2.90 mm to 7.50 mm diameter are of interest ...
