Effective thermal conductivity of composite pipe
Effective thermal conductivity of composite pipe
(OP)
I am using a specialized well bore anlysis program that calculates thermal profiles in down hole. The program requires a "k" thermal conductivity value for drill pipe as an input.
I am using a pipe that has insulation at different locations along its length. I would like to know how to calculate the effective "k" (thermal conductivity) of one pipe section "L". The pipe is basically steel with an insulation layer.

Do you mean that the insulation around the steel pipe is different or non-existent at various positions and, if so, what are they? It is very problematical to develop a socalled equivalent K . Mpre realistically you might need a piecewise solution using a different program for this.
I would strongly suggest that you explain exactly what you are trying to do and give us a sense of thermal boundaries and flow conditions, if any.
