Numerical modelling of Heat Pipe for enhancement of overall performance by variable working fluid and different glass material

This article uses several glass heat pipe types with varied profiles, meaning that simulations were run at different temperatures with respect to time. A higher temperature value is obtained by simulating an evacuated glass tube filled with soda lime silicate. The CAD model of the heat pipe used in this study was created with ANSYS. In order to observe different parameters impacting the heat pipe's performance in terms of thermal and phase transformation, the model has been simulated using ANSYS software on a fluent domain workbench. Additionally, it has been noted that, in comparison to earlier configurations, the 10 mm wall thickness of the copper pipe material engaged with the glass material exhibits greater convergence at the soda lime silicate glass evacuated tube.The outcomes are verified against the published base paper results. Among all the configurations tested, the soda lime silicate glass material configuration yields the highest convergence on all parameters when the fluid flow (octadecane) Nanofluid is placed within a heat pipe. We discovered that they provide superior mass transformation and temperature dispersion in the heat pipe's capillary tube. According to our investigation, the temperature of the erythritol nanofluid in the soda lime silicate glass evacuated tube in the heat pipe is greater.
