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.
