Card 9 - COSIM_CONV_LOAD Co-simulation Convective Load Definition
This optional card specifies the parameters and options for an exchange of solid temperatures and convective load data on the interface between your 3D thermal model and the external model.
Parameters: KODE, N1, T1,
T2
KODE
KODE is the code COSIM_CONV_LOAD (or 141)
N1
N1 is the COSIM_CONV_LOAD card ID. Cards with the same ID reference
the same convective load co-simulation interface.
T1 = NAME
T1 = NAME (or 1) specifies the convective load co-simulation
interface in T2.
T1 = EXTERNAL_SOLVER
T1 = EXTERNAL_SOLVER (or 5) specifies the external solver entity
name where you defined the external solver and the path to the external solver model
in T2.
T1 = LOAD_TYPE
T1 = LOAD_TYPE (or 2) Specifies the convective load type computed by
the thermal solver, with conditions and heat transfer data defined by the external
solver in T2.
T2 = THERMAL_STREAMspecifies the thermal stream as a convective load type.
T1 = CONV_LOAD_ID
T1 = CONV_LOAD_ID (or 3) specifies the ID in T2 of the thermal
stream for which the external solver defines the conditions and heat transfer
data.
T1 = FLOW_REVERSAL_CONDITIONS
T1 = FLOW_REVERSAL_CONDITIONS (or 4) indicates if the flow reversal
conditions are activated in the thermal stream definition.
T2 = TRUEindicates that the flow reversal conditions are activated in the thermal stream definition.T2 = FALSEindicates that the flow reversal conditions are not activated in the thermal stream definition.
T1 = MASSFLOW
T1 = MASSFLOW (or 6) specifies the external solver variable that
corresponds to the mass flow of the stream in T2. This variable is computed by the
external solver and transferred to the defined thermal stream computed by the
thermal solver.
T1 = TINLET
T1 = TINLET (or 7) specifies the external solver variable that
corresponds to the inlet temperature of the stream in T2. This variable is computed
by the external solver and transferred to the defined thermal stream computed by the
thermal solver.
T1 = PRESSURE
T1 = PRESSURE (or 8) specifies the external solver variable that
corresponds to the absolute pressure of the stream in T2. This variable is computed
by the external solver and transferred to the defined thermal stream computed by the
thermal solver.
T1 = HTC or or HTCB
T1 = HTC (or 9) or HTCB (or 10) specifies the
external solver variable that corresponds to the stream's heat transfer coefficient
in T2. In the case of two-sided streams, HTC and HTCB specify the heat transfer
coefficient for the first and second side of the two-sided thermal stream,
respectively. This variable is computed by the external solver and transferred to
the thermal solver thermal stream definition.
T1 = HEATPICKUP or HEATPICKUPB
T1 = HEATPICKUP (or 11) or HEATPICKUPB (or 12)
specifies the external solver variable that corresponds to the heat pickup of the
stream. It is additional heat pickup in the fluid flowing in the stream, as a heat
power per unit area of the thermal stream selection. In the case of two-sided
thermal streams, HEATPICKUP, and HEATPICKUPB specify the heat pickup for the first
and second side of the two-sided thermal stream, respectively. This variable is
computed by the external solver and transferred to the defined thermal stream
computed by the thermal solver.
T1 = SWIRL_RATIO or SWIRL_RATIOB
T1 = SWIRL_RATIO (or 15) or T1 = SWIRL_RATIOB(or
16) specifies the external solver variable that corresponds to the swirl ratio for
total temperature corrections in T2. The thermal solver uses the specified value to
relate total temperatures and relative temperatures In the case of two-sided thermal
streams, SWIRL_RATIO, and SWIRL_RATIOB specify the swirl ratio for the first and
second side of the two-sided thermal stream, respectively. This variable is computed
by the external solver and transferred to the defined thermal stream computed by the
thermal solver.
T1 = SWIRL_VELOCITY or SWIRL_VELOCITYB
T1 = SWIRL_VELOCITY (or 13) or T1 = SWIRL_VELOCITYB
(or 14) specifies the external solver variable that corresponds to the swirl
velocity for total temperature corrections in T2. The thermal solver uses the
specified value to relate total temperatures and relative temperatures In the case
of two-sided thermal streams, SWIRL_VELOCITY, and SWIRL_VELOCITYB specify the swirl
ratio for the first and second side of the two-sided thermal stream, respectively.
This variable is computed by the external solver and transferred to the defined
thermal stream computed by the thermal solver.
T1 = SOLIDTEMP
T1 = SOLIDTEMP (or 17) specifies the external solver variable that
corresponds to the solid temperature. The solid temperature is computed by the
thermal solver and transferred to the external solver.
