GT-SUITE TIPS
Guidelines about use of number of temperature zones in combustion model
Use (1) "single-temp" in "EngBurnRate" while calibrating predictive combustion model with
single cylinder measured cylinder pressure trace analysis, (2) "two-temp" in "EngBurnRate"
while determining burn rate from single cylinder measured cylinder pressure trace analysis, (3)
"two-temp" in non-predictive and semi-predictive combustion model while calibrating full
engine model, and (4) there is "no need" to define this parameter in predictive combustion
models as these models use multi-zone combustion model.
Compare apparent heat release rate (AHRR) and not burn rate
In GT-Power, burn rate is the rate at which fuel and air molecules are transferred to burned
zone from unburned zone and begin to participate in the chemical reactions. Heat release rate
is the rate at which energy stored in fuel molecules is released in cylinder as thermal energy.
This quantity differs from the burn rate because fuel-air mixture entering begins to participate
in the chemical reactions does not break down instantly into its final products of combustion.
Due to this reasons, sometimes it may happen that even though GT-Power predicted burn rate
is matching with burn rate from measured cylinder pressure trace; but HRR/AHRR is not
matching. Subsequently, relevant performance parameters will not match. If you miss to see
the AHRR behavior, you will not be able to identify the reasons behind this mismatch. That's
why it is always better to compare AHRR instead burn rate (e.g. during DIPulse calibration).
Over-constrained situation in EngCylFlow object
Do you know that when you define geometric parameters in "EngCylFlow", it has to maintain
consistency with the compression ratio, bore, stroke, and clearance height defined in
"EngCylGeom"; and the formula is mentioned below. In many instances, this leads to an over-
constrained system in which one of the attributes must be adjusted to maintain the integrity of
the solution. There are three methods by which this can be handled. Refer to Help document of
EngCylFlow object for more info.
Use of super-parameter in case setup
Super-parameter feature in Case Setup allows user-defined dropdown parameters. Other
parameters can be made "dependent" on a super-parameter such that the super-parameter
acts as a singular independent variable controlling multiple parameters below.
