19: Fluid Flow Computations

Command	Purpose
avl_link	Link to the AVL Indicom combustion analysis system.
blend_scales	Manage fuel weighing operations using load cells, including controlling fill valve operations and computing fuel rates based on sampling processes.
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 using inputs from a specification file.
critical_flow	Compute air mass flow on a continuous basis.
dummy_fr	Simulate fuel reading events by processing an event name to mimic the behavior of a fuel reading device task for testing purposes.
emcon_comm	Communicate with an AVL EMCON6 system to manage dyno control, handling data exchange via sockets, parsing configuration files, and processing input and output variables.
fa_total	Perform continuous fuel and air flow totalizing computations for engine performance, including summing rates and calculating metrics like air-fuel ratio.
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 and perform actions based on cylinder states.
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 gaseous mass flow rates for up to 8 meters based on input specifications.
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	Display or return the value of a computed expression in the specified units.
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 gas mass flow rates continuously for a Laminar Flow Element based on specified inputs and configuration.
oil_scales	Measure the oil consumption rate of a load cell based measurement device.
scales	Control the fuel scale system by managing fill valve operations, weight selections, and timing for fuel readings based on transition events.
subsonic	Compute continuous gas flow rates for subsonic venturi meters based on inputs from a specification file, performing real-time calculations and handling events for updates.
take_auto	Request a single fuel reading with automatic weight selection.
take_autos	Request continuous fuel readings and set the fuel weight selection to automatic.
take_dum_fr	Take a dummy fuel reading.
take_fr	Request a single fuel reading and optionally specify a fuel weight.
take_frs	Request continuous fuel readings and optionally specify a fuel weight.
urea_flow	Collect and process urea flow data, including monitoring total flow and handling fault events in a continuous background service.
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 for a single engine manifold on a continuous basis.
volef2	Compute volumetric efficiency for an engine manifold on a continuous basis using variables specified in a configuration file, focusing on engine displacement as a variable.
