Prediction of turbulent heat transfer and fluid flow in 2D channels roughened by square and round ribs

Introduction of roughness by ribs in flow passages is a popular method of enhancing heat transfer in the cooling passages, e.g., of turbine blades and combustors. It is essential to accurately predict the enhancement of heat transfer generated by the ribs to ensure good design decisions. In most of the studies square ribs have been considered, but in practice such ribs may appear rounded due to im

Internets kollektiva minne är företagens stora framtidsutmaning

Jag ser med spänning fram emot när dagens ungdomsgeneration kommer ut på arbetsmarknaden. Ni vet, den generation som får utstå vuxensuckar på grund av fascinationen av självcentrerade selfies-porträtt och mängden ogenomtänkta bilder från vilda tonårsfester.

Robotics in rehabilitation

Robotics in rehabilitation provide considerable opportunities to improve the quality of life for physically disabled people. However, practical results limited, mainly due to the need for developing new robotics concepts where people are where they are working in separeted areas. This paper reveals some of the developments needed and presents two projects currently underway at Lund University. The
