Managing Fingerprints

/0 Comments/in /by

Law enforcement professionals may appreciate fingerprints that are easy to spot, but the rest of us don’t. Stainless steel is an amazing material that provides beauty and permanence in a variety of applications. Stainless steel building envelopes will last as long as the building stands. While fingerprints are seldom an issue outside the building, interior elements like column covers and elevators are exposed to considerable pedestrian traffic. For these applications, managing fingerprints becomes important.

Flow Visualization and Comparison of the Evaporation Heat Transfer Coefficient for Smooth and Enhanced Surface 1EHT Horizontal Tubes

/0 Comments/in /by

Flow visualization of flows near a heat transfer tube and evaporation heat transfer results of Vipertex 1EHT tubes are compared to Smooth Tubes have been presented at ECCE10 (10th European Congress of Chemical Engineering).

The evaporation heat transfer coefficient enhancement ratio (for the range considered for flows using R410a), for the 1EHT tube is approximately 1.4

The evaluation shows that depending on the applied constraints, different benefits can be obtained using Vipertex® tubes, including: – a heat duty increase of up to 19%, an 18-30% reduced flow rate to achieve the same heat duties, or a change in the geometry to achieve a 8-9% increase in heat transfer at the same pumping power.
