METHOD AND SYSTEM FOR CALCULATING PRESSURE LOSSES TAKING THERMAL EFFECTS INTO ACCOUNT

摘要

the present invention relates to a method for the calculation of loss of prestresscreated by a fluid in a channel with a thermal profiledetermined. we shall carry out the following steps:it is a database (bd) that the rheology ofunder different fluid as a function of temperature.we segmented the thermal profile (2, 3) into sections (4, 5, 6, 7) andto determine a value representative of the temperature (t1, t2, t3, t4) for thethe fluid in each section.it uses the database to determine the rheology of the fluidin each section the representative temperature.it is calculated and added to each line lossesin view of rheology was determined.
