SINDA예제[열역학]JT cooling

C&R tools are routinely used to model the complexities of JT cooling systems, as either blow-down systems or closed cycles (e.g, Rankine or Gifford-McMahon). Because they provide compact and vibration-free cold heads, such coolers are popular for cooling of sensors and electronics including cryogenic and MEMS (microcooling) applications.

The combination of SINDA/FLUINT and SinapsPlus® is used for system-level schematics, or SINDA/FLUINT plus FloCAD® (an optional Thermal Desktop® module) for detailed modeling of cold heads and other heat exchangers.

Key features relevant for analyzing JT cooling systems include:

• 
  
• Real-gas and saturation dome properties readily available for the most commonly used fluids including hydrogen, helium, nitrogen, argon, CO2, methane, and propane. Additional and custom fluids (e.g., mixed gas coolers) descriptions can be created by C&R or the user.
• Complex heat exchangers in cold heads and in multi-stage coolers (regenerators, recuperators, intercoolers)
• Transient analyses including tank blow-down and structural cooldown (start-up analyses)
• Expansion into the dome including two-phase heat exchange. See also Two Phase Analysis.
• Arbitrarily complex control systems (PID etc.) applied to valves, compressors, etc.
• Access to parametric modeling and Advanced Design Modules (optimization and sizing, automated model calibration to test data, reliability and statistical design, etc.)
