Infrared thermography observations of crystallization fouling in a plate heat exchanger

چکیده
Heat exchanger performance is significantly reduced in the presence of impurities one or both fluid streams, frequently by deposits inversely soluble salts. Accordingly, immense efforts were and still are spent to combat, predict, investigate such fouling problems mitigate reduction heat transfer performance. In this study, calcium carbonate crystallization a corrugated plate was investigated. Fouling monitored using temperature flow measurements, and, for first time, coupled with infrared thermography observations. We show clear measurable local difference between clean fouled conditions, regardless operating conditions. Infrared measurements permit conclusions about distribution spatial location areas severe fouling. Compared state, completely skewed isotherms after point out channel blockage obstructions, resulting large scale re-distribution within channel. The presented results exhibit benefit approach studies serve as foundation future research dynamic operation, transient response, computational models.

Heat Transfer Analysis of Nanofluid in a Sine Wave Plate Heat Exchanger
Heat transfer is one of the most critical processes in the industry, and by increasing the efficiency of the heat exchanger, energy consumption of systems will be reduced. Very tiny particles in nanoscale dimensions, when uniformly dispersed and stably suspended in the base fluid, efficiently improve the thermal properties of the base fluid. With the help of nanofluids, the heat transfer rate i...

متن کاملHeat transfer enhancement in a spiral plate heat exchanger model using continuous rods
This study presents an innovative and simple way to increase the rate of heat transfer in a spiral plate heat exchanger model. Several circular cross-section rods, as continuous vortex generators, have been inserted within the spiral plate heat exchanger in the cross-stream plane. The vortex generators are located at various azimuth angles of α=30◦, 60◦, 90◦, and 120◦ with non-dimensional diame...
