Abstract

Purpose

In this study, closed-form solutions are presented to investigate thermohydraulics of liquid films in a rotating heat pipe. The film thickness is expressed as a function of flow rate.

Design/methodology/approach

Further, sensitivity of both film thickness and flow rate to the length of the rotating heat pipe can now be investigated using the explicit expressions presented here.

Findings

To make it easier for practical application, an approximate solution is presented on top of the exact solution.

Originality/value

Both approximate and exact solutions are then applied to note that results are in good agreement when compared to those available in the literature.
