Experimental Study on air-Dehumidification Performance using Supersonic Nozzle

Project Overview

Natural gas is most often mixed with significant quantities of water and other unwanted solid particles. These unwanted particles can cause many serious problems to the carrier means, instrumentations and flow transmission itself. Supersonic nozzles are commonly used to purify the air. Being an innovated technology, it is employed to overcome the deficit of traditional methods, related to gas dynamics, thermodynamics and fluid dynamics theory. In this project, an indoor test rig will be built to study the dehumidification process of moisture fluid. Humid air is chosen for the study. The working fluid will be circulating in an open loop, which has provision for filtering, metering, and humidifying. A stainless steel supersonic separator will be designed and constructed together with the C-D nozzle system. De-humidification process performance of humid air using supersonic nozzle will be studied. The positioning of shock wave, predicted by simple one-dimensional theory, will be quantified to become benchmark of droplet separation position. Finally, the air pressure that is recovered after shock inception will be evaluated.

Project Objectives

  • Prepare new designs for supersonic nozzle to indicate that the water can be efficiently separate from the natural gas.
  • Test multiple designs for supersonic nozzle and compare the result between them in efficiency aspect. 
  • Examine different shapes of the nozzle and predict their effect on water-particle interaction.
  • The positioning of shock wave, predicted by simple one-dimensional theory, will be quantified to become benchmark of droplet separation position compared with the results of numerical simulation.
