Identification Of Ships Propulsion Engine Operation By Means Of Dimensional Analysis

Abstract

The following article presents the metod of determining the ship s propulsion engine operation basing on the engines work parameters by means of dimensional analysis .The ships propulsion engine activity, as noticed by J. Girtler in his works [4,5], can be used for its diagnostics. of ship propulsion. Diagnostics engines increases safety of ships movement and at the same time protects the sea environment from pollution in case of its sinking. According to Girtler engine operation can be considered as, a new physical quantity of dimension Joul multiplied by second [ ] s J ⋅ . This quantity can be determined on the basis of algebraical diagram of dimensional analysis constructed by S. Drobot. This diagram allows to control the correctness of conclusion rules, in respect of mathematics, used in numerical functions of ship propulsion engine operation.
