An exhaust wet scrubber was experimentally investigated based on the heat transfer analysis for gas-liquid two-phase flow. Different inlet operating conditions for gas phase such as temperature 24- 650 ºC, 113.3 standard litre per minute flowrate and 5 mm orifice plate holes were tested. The purpose of the orifice plate is to break bubbles into smaller ones, leading to more heat transfer due to the increase of the bubble surface area. Moreover, bubble motion is recorded using a high-speed video system. An image processing software (ImageJ) is processed both images and videos effectively to track bubbles, remove image noise, and set image threshold. Bubble dynamic and thermal parameters and non-dimensional numbers were calculated using MATLAB program. The measured parameters will be used to develop a heat transfer model for the wet scrubber.
