19: Fluid Flow Computations

Command Purpose
avl_link Link to AVL Indicom combustion analysis system
blend_scales This task provides control functions for a directly controlled load cell fuel system. These functions include fill valve operation, and timing of a fuel reading.
change_res Change the formatted resolution of a variable or a list of variables
cfv_1065 This task computes the air mass flow on a continuous basis.
critical_flow This task computes the air mass flow on a continuous basis.
dummy_fr

This program simulates the FR_IP events that would come from a fuel reading device task. It is used to simulate a reading when we don‘t really want to take one. This supports the’ @PAM_DATAPOINT keyword of gp_test.

The program is spawned with an argument that is the event name that will be sent to trigger the start of a reading.

fa_total

Fuel Totalizing Computation

fr_log Sets fuel reading log file name.
gas_blend Compute the ratio of three input gas streams to meet a required Heating Value and Methane Number. The outputs will be the ratios of each input stream, the Heating Value, and Methane Number of the resulting composition.
gas_mix Compute the gas composition of a stream which is produced by mixing two or more gas streams. The composition and mass flow of each of the input streams must be known and specified. The resulting mixed stream composition and mass flow are the outputs of this application.
gasfl Air Mass Flow Computation
generic_scales This task provides control functions for a directly controlled load cell fuel system. These functions include fill valve operation, and timing of a fuel reading. The outputs include the consumption rate, hp-specific consumption, and error statistics of the linear regression performed on the load cell value during the reading.
get_comp Get the value of a computed expression
lc_scales This task provides control functions for a directly controlled load cell fuel system. These functions include fill valve operation, and timing of a fuel reading.
lfe The lfe task computes the air mass flow on a continuous basis for a laminar flow element.
scales This task provides control functions for a directly controlled fuel scale system. These functions include fill valve operation, weight selection, and timing of a fuel reading.
subsonic This task computes the air mass flow on a continuous basis.
take_auto Take one Fuel Reading with automatic weight selection
take_autos Take continuous Fuel Readings with automatic weight selection
take_dum_fr Take a dummy fuel reading
take_fr Take a Fuel Reading
take_frs Take Fuel Readings continuously
urea_flow Measure urea flow rate
Vcone_flow This task computes the air mass flow on from a V-cone meter.
venturi Air Mass Flow Computation for nozzle
volef Volumetric Efficiency Computation
volef2

Volumetric Efficiency Computation

This version (volef2) uses a spec file into which you specify an engine displacement variable rather than the number of cylinders.
