Confined and unconfined nucleate boiling of HFE7100 in the presence of nanostructured surfaces
(2018-02-01)
This article presents experimental results for the confined and unconfined nucleate boiling of saturated HFE7100 (C4F9OCH3) at atmospheric pressure and using nanostructured copper discs as heating surfaces. The nanostructures ...
A Method for Measuring Contact Angle and the Influence of Surface-Fluid Parameters on the Boiling Heat Transfer Performance
(Asme, 2020-09-01)
An experimental apparatus and a computational routine were developed and implemented in order to obtain the sessile drop images and the contact angle measurement for different fluids and surface conditions. Moreover, ...
Desenvolvimento de método para a análise quantitativa da rugosidade de substratos cerâmicos argilosos
(Universidade do Vale do Rio dos Sinos, 2021-08-26)
The diversification of materials used as substrates in Civil Construction hinders the standardization of building systems, increasing the probability of pathological manifestations. An example of this is the detachment of ...
