Airflow visualization and air purifier positioning optimization in potentially COVID-19 contaminated classrooms

Design of modern interactive and ergonomic home air purifier

Introduction: The subject of this research is having healthy air and its challenge is air purification to have this type of air. Healthy air is free of any pollutants, including odors, harmful gasses, dust, and viruses, especially corona. This healthy air is provided by a purifier device. One of the problems of metropolises is the lack of healthy air, which is one of the most important human ne...

economic optimization and energy consumption in tray dryers

دراین پروژه به بررسی مدل سازی خشک کردن مواد غذایی با استفاده از هوای خشک در خشک کن آزمایشگاهی نوع سینی دار پرداخته شده است. برای آنالیز انتقال رطوبت در طی خشک شدن به طریق جابجایی، یک مدل لایه نازک برای انتقال رطوبت، مبتنی بر معادله نفوذ فیک در نظر گفته شده است که شامل انتقال همزمان جرم و انرژی بین فاز جامد و گاز می باشد. پروفایل دما و رطوبت برای سه نوع ماده غذایی شامل سیب زمینی، سیب و موز در طی...

Electrostatic Fluid Accelerator and Air Purifier – The Second Wind

Transformation of ionic pump (electron wind, Electrostatic Fluid Accelerator) technology from curious laboratory experiments to practical industrially acceptable devices requires pushing the basic technology to its physical limits. This paper presents a description of main design optimization options. A numerical modeling study demonstrates the effect of geometry and voltage distribution on the...
