Capabilities

  • Calculation of Q, U, and outlet temperatures
  • Calculation of heat transfer surface
  • Calculation of core height, core width (for a specified heat load)
  • Calculation of flow rates (for a specified heat load)
  • With respect to core height, weight, width, and flow rates or a combination of these variables.
  • With respect to core height, width, and flow rates or a combination of these variables. The program evaluates all viable configurations within the limits that you provide to arrive at a number of feasible solutions listed in the order in which they satisfy an optimization criterion. Criteria include minimum pressure drop, minimum heat transfer surface area, minimum power, or a combination of these.
  • Single-Phase Analysis
  • Two-Phase Analysis
  • Non-condensable
  • Rectangular, Triangular, Trapezoidal, and Wavy. Custom fin types can be supplied in the form of j/f characteristic curves.
  • Plain, Serrated, and Herringbone. Custom fin types can be supplied in the form of j/f characteristic curves.
  • Core height, core width, number of plates, plate thickness, plate thermal conductivity
For each streams:
  • Fin profile, Thickness in passage, Height in passage, Pitch, Fin thermal conductivity, K-factor, Fluid density, Specific heat, Viscosity, Thermal conductivity, (or a fluid selection from the INSTED/Database)
  • Total heat transfer rate
  • Total heat transfer area
  • U, UA
  • Effectiveness

  • A design realization, showing the number of plates, heat transfer area, pressure losses, flow rates, and dimensions satisfying the sizing requirements.
Several design realizations as a function of:
  • The number of plates
  • The heat tranfer rate
  • The pressure losses
  • The flow rates
  • The geometric dimensions (core height and width)
