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.
