Santex Rimar to present innovative solutions at ITMA 2023
Santex Rimar , the leader in technology for textile finishing of high-quality knitted fabrics ,
will exhibit its products at ITMA 2023 in Italy . The company ’ s products stand for Swiss and
Italian innovative solutions based on the real need of the customer and for high productivity and sustainable production . Santex ’ s goal is to maximise performance with low energy consumption to achieve low residual shrinkage , smoother handle , and silk-like appearance . The lines are equipped with various energy saving options , benefiting customers through sustainable production and low
CO 2 levels , the company said in a press release . With Santaframe and Santacompact RDA , Santex Rimar will present its well-known stenter frame in combination
with the felt belt compacting machine for the finishing of high-quality open-width knitted fabrics as well as applicable for woven fabrics , at ITMA . The outstanding performance and production of the Santaframe are based on continual development using the latest advances in thermodynamics , allied to the changing need of customers . The heating system is located above the fabric web in the upper part of the 2 m treatment zone . An air circulation fan draws the air from the nozzles and the treatment zone through the filter panels and guides it along a short path to the heat exchanger , from where it is fed into the nozzles .
Grad student achieves influential discovery in heat transfer
MAE graduate research assistant Suhas Tamvada has made a major discovery in the field of heat transfer , a breakthrough that addresses a question debated in nucleate boiling science for decades . The research and its findings have recently appeared in the International Journal of Heat and Mass Transfer . Tamvada ’ s research , conducted alongside UF MAE ’ s Dr . Saeed Moghaddam and scientific consultant Daniel Attinger , owner of Struo LLC , addressed the two prevailing theories regarding critical heat flux ( the maximum amount of heat that can be transferred from a surface to a liquid while boiling ). The proposed theories on the existence of this limit had to do with hydrodynamic instability ( a phenomenon happening away from the boiling surface ) and evaporation momentum force theory ( happening on the surface itself ). These two theories predicted roughly similar critical heat flux values , but the team ’ s paper shows that the evaporation momentum limit is 3 to 4 times higher than previously thought . Tamvada ’ s paper describes how , though these are two contrasting phenomena , they both are present throughout the entire boiling process . However , his research showed that , provided with the right experimental conditions , it is possible to overcome the limit imposed by the hydrodynamic instability and establish a flow condition wherein the evaporation momentum limit can be observed as the ultimate limit .
