Subdivision of Heat and Mass Transfer, and Fluid Engineering

Subdivision of Heat and Mass Transfer, and Fluid Engineering, provides a forum for communication and networking among engineers and scientists who share interests in research and technological development associated with various transport phenomena in chemical process industries.Our mission is to contribute to the advancement of science and engineering for complex phenomena in chemical plant equipments, such as fluid mixing, heat and mass transfers, chemical reactions, and their interrelated phenomena, from a view point of fluid dynamics by experimental and numerical techniques.

We organize a seminar and a symposium every year in the autumn meeting of the Society of Chemical Engineers, Japan, in order to exchange information and enhance the knowledge of the members. We have also organized the International Workshop on Process Intensification (IWPI) since the first workshop held in Kobe, 2006. The workshop discusses process intensification whose essential backgrounds are transport phenomena.IWPI has held once in two years, in Tokyo (2008) and Fukuoka (2010).In 2012, IWPI has first crossed the sea to Seoul (2012) and will jump out from Asia.

The subdivision of Heat and Mass Transfer, and Fluid Engineering is the core in the Division of Fluid Particle Processing, consisting of other four subdivisions of Mixing Technologies, Fluidization, Bubble-Droplet-Particle Dispersion Engineering, and Particle Processing, as well as our subdivision. Since most of our members belong to other subdivisions and study diverse subjects and applications, this diversity is the strong point of the subdivision of Heat and Mass Transfer, and Fluid Engineering in terms of scientific and technological discussions. We hope that many people engaged in chemical engineering join our subdivision and participate in our activities.

Mixing Subdivision

Recently, new mixing systems have been developed and mixing technology is diversifying over various fields for instance chemicals, foods, pharmaceuticals, cosmetics. In addition, evaluation and design of mixing equipments from new view points by means of highly developed methods of measurements and analyses including methods of numerical simulations. Members of Mixing Subdivision from makers and users of mixing equipments and academic researchers are continuing to discuss various kinds of issues described above in order to innovate in the precisely developed mixing technology.

The focused group on Bubbles, Drops, and Particles Dispersion Engineering

In various engineering fields, we often encounter a wide variety of processes and apparatuses where dispersed bubbles, drops and particles suspended in fluids play a key role. The Working Party of Bubbles, Drops, and Particles Dispersion Engineering tackles engineering problems related to the dynamics of dispersed bubbles, drops and particles. Our specific goals are as follows:

(1)To establish rational designing and operating technologies for industrial equipment and processes consisting of a wide variety of dispersed and continuous phases.

(2)To explore fundamental mechanism of multiphase fluid flows including heat and mass transfer intrinsic to chemical equipment and processes.

The understanding of the dynamic motion of dispersed bubbles, drops and particles is key to accomplish these aims. Also, state-of-the-art multi-scale, hierarchical approaches are required for understanding myriad multiphase flow. Implementation can be studied either through novel experimental techniques or novel computational fluid dynamics (CFD) algorithms. The Working Party of Bubbles, Drops, and Particles Dispersion Engineering provide a valuable forum for scientists and researchers in the field of various dispersion engineering to exchange information, discuss research topics, ascertain challenging problems and offer new ideas for future studies and developments. We welcome you to join The Working Party of Bubbles, Drops, and Particles Dispersion Engineering.

Subdivision of Powder Process Engineering

Behaviors of particulate materials and its bulk materials, POWDER, in a chemical process are complex. We share the common interest aimed at creation of high quality, high functionally and high value-added particulate materials, innovation of unit operations for powder processing, invention of powder processes and environmental preservation. Our activity offers a place where we can exchange information, results and ideas to create, innovate and invent them based on microscopic and/or macroscopic analysis of phenomenon.
