Abstract

•A visual experimental rig was designed to observe particle deposition on heat exchanger.•A weight method including a moveable analytical balance was adopted to measure weight of deposited particles on heat exchanger.•Particle deposition on a wavy fin-and-tube heat exchanger mostly occurs on the leading edge of fins and the front part of tubes.•Decreasing fin pitch or increasing particle concentration may lead to more particle deposition.•Increase of air velocity promotes particle deposition at lower air velocity while restrains particle deposition at higher air velocity.
