摘要: The effect of gold nanoparticles on the formation gas bubbles top a stainless steel tube is investigated in this work. Unlike other observations bubble dynamics under evaporation or boiling conditions, which are caused by surface modification due to particle sedimentation, work reveals unique phenomenon enhanced pinning triple line and improved wetting suspended liquid phase. Detailed characteristics related growth inside pure water nanofluids, including line, variation instantaneous contact angle, height, volume expansion rate, analyzed. shape found be good agreement with predictions Young−Laplace equation using experimental captured radius height as two known inputs. tensions resultant force balance at believed responsible for modified ...
