Particulate Multiphase Fluids Engineering Laboratory

This lab is dedicated to the fundamental study and technology development of particulate multiphase flows. Our research projects cover dynamics of particulate multiphase flows, particulate pollution control, nano/micro-powder technology, and membrane distillation.


Evaporating Sprays in Gas-Solid Flows

The objective of the study is to understand the fundamental mechanisms and microstructures of evaporative liquid spray jets in gas-solid suspension flows. This study is focused on turbulence mixing and phase interactions among gas, solids, and evaporative liquid droplets (generated from jetting), which is essential to the improvement of the design, predictability, efficiency, and control of multiphase flow jet systems in petroleum refinery, coal gasification, polymer production, and other related industries





Rotating Fluidized Bed Wet Scrubber (RFBWS)

This is a new project that is being initiated as a part of the growth of particle technology research activities at NJIT. Particle filtration is an important area of tremendous economic and environmental significance. Most industrial processes involving articulate materials (and many other processes that generate particulate waste materials) require filtration of fine particles at various stages, including the filtration from waste streams that include fine particles. While this is a traditional area of particle technology, there is need for improved performance of these devices, including ability to filter very fine, micron sized particles. In response to that need, we have developed a novel concept of rotating granular filtration. This device is specifically designed for removal of particulate (and other air-borne) materials from air streams. The most interesting characteristic of this device is that it is self-cleaning.



Ultrasonic Enhancement on Membrane Distillation

Membrane distillation (MD) takes advantage of utilization of low heat resources (typically known as waste heat) from many industry processes and hence significantly reduces the energy cost for membrane separation. The objective of this project is to carry out an experimental and theoretical investigation on membrane distillation with tubular modules. In addition, the project intends to obtain an understanding on the effects of ultrasonic irradiation on the enhancement of permeate mass flows in tubular-module based membrane distillation systems. The proposed study will be based on experimental investigations with aid of modeling explanation for the hydrodynamic characteristics as well as separation effectiveness of the membrane distillation system.
