Oil coking analysis for e.g. jet engine, involves realizing oil flow, so that conduit`s inner wall has non-wet portion, and heating conduit, so that part of portion has temperature lower than minimal temperature of wet portion

摘要

The process involves realizing oil flow (20), so that an inner wall (18) of a conduit (10) has a non-wet portion (36) by the oil flow. The non-wet portion extends along the conduit. The conduit is heated so that a part of the non-wet portion has a temperature lower than a minimal temperature of a wet portion (38) of the inner wall of the conduit, for each cross section of the conduit.
