calcKristCa.Rd
Calculate incremental hull (roughness) resistance coefficient
(Ca
) (dimensionless) using the Kristensen method.
calcKristCa( shipType, actualDisplacement, tankerBulkCarrierGCargoShipTypes = c("tanker", "general.cargo", "chemical.tanker", "liquified.gas.tanker", "oil.tanker", "other.tanker", "bulk.carrier"), containerShipTypes = c("container.ship") )
shipType | Ship type (vector of strings, see |
---|---|
actualDisplacement | Actual loaded displacement (vector of numericals,
m^3) (see |
tankerBulkCarrierGCargoShipTypes | Ship types specified in input
|
containerShipTypes | Ship types specified in input |
Ca
(vector of numericals, dimensionless)
Models the effect of realistic hull roughness on resistance, which is not captured in the frictional and residual resistance coefficients from tank towing operations.
This method this requires ship types to be grouped. Use the
tankerBulkCarrierGCargoShipTypes
, containerShipTypes
grouping
parameters to provide these ship type groupings. Any ship types not included
in these groupings will be considered as miscellaneous
