SmartPM™ is performance monitoring and predictive maintenance software for shell-and-tube exchanger networks. This webinar introduces SmartPM and highlights the new capabilities in version 4.1.

With this software, you can

  • connect SmartPM to OSIsoft PI System™ for two-way data transfer
  • easily reconcile and simulate data
  • identify ways to save energy and manage throughput through exchanger cleaning
  • decide which exchangers not to clean at turn-around
  • improve network performance when revamping exchangers

We also demonstrate the new functionality of SmartPM through a case study.

HTRI gathered experimental data for a plate-and-shell exchanger at the Research & Technology Center (RTC). These data provided the opportunity for HTRI to extend its CFD simulation experience to plate heat exchanger types. The results provide additional insights about the flow distribution and port pressure drops. In this webinar, we discuss the efficient computational approach and the results that reiterate the high thermal effectiveness of the plate exchanger type and reveal minimal channel-by-channel flow variation. Computed port pressure losses confirm current plateside correlations and point to alternative formulations for shellside port pressure losses. The computational approach is well suited for additional studies of larger plate packs and other port configurations.

To ensure reliable data collection, HTRI always seeks to improve test methods and incorporate innovative techniques. Recently installed at the Research & Technology Center, the Air-cooled Unit (ACU) has motivated us to develop better ways of collecting airside measurements for both forced- and natural-draft testing. Accurate measurements for natural-draft (fans off) testing can be especially challenging due to the relatively low airside flow rates.

Determining the precise type and quantity of instruments required for airside natural-draft testing has taken some time. HTRI has investigated various methods of measuring temperature, pressure, and flow rates, including the use of some unique gauges and probes like the hot-wire anemometer and Kiel probe. Understanding the way these instruments work and their limitations help engineers improve measurement quality.

Innovative methods like high-speed camera imaging and smoke testing on the ACU help us visualize and quantify heat plumes that would otherwise be invisible. An industrial “box” chimney with integrated instrument systems has also allowed us to investigate the effects of chimneys on natural-draft flow.

HTRI continues to enhance data collection for natural draft in the ACU. We look forward to eventually analyzing natural draft in alternate flow configurations, including hot-air recirculation, maldistribution, and induced draft configurations.
