ANY NUMBER OF FLUIDS WITHIN THE SAME NETWORK
Fluids are specified at each
input boundary and the software takes care of composition changes.
This means you can analyse networks containing as many fluids
as you require. Physical properties of mixtures at flowing conditions
are estimated as needed. Networks can also be analysed containing
multiple fluids where mixing does not occur. For example, you
can analyse cooling water and process streams within the same
flowsheet.

FLUID EQUIPMENT
The performance of almost any
type of line equipment can be determined, for example:
- Pump duty, efficiency, NPSH,
power
- Fan or compressor duty
- Control valve opening
- Heat change across heat exchangers,
pipes
- Safety relief valves
- Manual valves
- Orifice plates
- Filters
- Sprinklers and nozzles
- and much more
TOTAL HEAT BALANCE
Fluid temperatures are specified
only at boundary components. All other temperatures as well as
fluid phase states are calculated by the software. Temperature
effects of pressure changes, heat loss or gain from the surroundings
and heat exchange made at each network component make heat transfer
an automatic part of network flow calculations.Fluid temperatures are specified at boundary
components; all other temperatures as well as fluid phase states
are calculated by the software.
COMPRESSIBLE FLOW
Gas calculations make no simplifying
assumptions of ideality, adiabatic or isothermal processes etc.
Pressure losses are determined by solving the momentum and physical
property equations simultaneously. This means more accurate results,
particularly at higher Mach numbers.
2-PHASE LIQUID/SOLID FLOW SIMULATION
Non-Newtonian and Settling Slurry
This module is planned for release
May 2006. Planned capabilities include:
- Power Law Fluid correlation
- Pseudoplastic, Dilatant (solution according to Darby)
- Bingham Plastic correlation
(solution according to Darby)
- Yield Pseudoplastic (solution
according to Herschel-Buckley or Chilton & Stainsby)
- Heterogeneous Settling Slurries
correlation (solution according to Wasp etc)
The fluids databases will accommodate
the necessary data for these simulations such as power law coefficients,
particle size distribution, viscometer readings.
2-PHASE LIQUID/GAS FLOW SIMULATION
Currently only liquid mixtures or gas mixtures are allowed.
2-phase liquid/gas will be available end of 2006.
