19: Fluid Flow Computations

Command	Purpose
avl_link	Link to the AVL Indicom combustion analysis system.
blend_scales	Perform 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.
cf_scales	Provide control functions for a load cell fuel system that also uses a continuous flow meter and flow control valve.
cfv_1065	Compute air mass flow on a continuous basis per the 1065 standard.
critical_flow	Compute air mass flow on a continuous basis.
dummy_fr	Simulate the FR_IP events that would come from a fuel reading device task.
emcon_comm	Communicate with an EMCON6 AVL Dyno system.
fa_total	Fuel Totalizing Computation.
fr_log	Set a 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_distribution	Set the values of CyFlex array variables that contain information about emission gases.
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	Compute Air Mass Flow.
generic_scales	Perform 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	Perform control functions for a directly controlled load cell fuel system. These functions include fill valve operation, and timing of a fuel reading.
lfe	Compute the air mass flow on a continuous basis for a laminar flow element.
oil_scales	Measure the oil consumption rate of a load cell based measurement device.
scales	Perform control functions for a directly controlled fuel scale system. These functions include fill valve operation, weight selection, and timing of a fuel reading.
subsonic	Compute the subsonic 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 continuous Fuel Readings.
urea_flow	Measure urea flow rate.
Vcone_flow	Compute the air mass flow on from a V-cone meter.
venture	Compute Air Mass Flow for a nozzle.
volef	Compute Volumetric Efficiency.
volef2	Compute Volumetric Efficiency. This version (volef2) uses a spec file into which you specify an engine displacement variable rather than the number of cylinders. This can be used for 2-cycle engines by specifying a value of displacement that is twice the actual displacement.
