Nowadays, energy consumption increases so it is necessary to enhance the efficiency and performance of heat transition. The effects perforated twisted tape on transfer coefficient, effectiveness, Nusselt number, pressure drop are studied numerically. Modeling exchanger with applied where finite volume method utilized perform setup complete solution. numerical results validated previous experime...

In [2] it has been shown that infinitary strong normalization (SN∞) is Π11-complete. Suprisingly, it turns out that infinitary weak normalization (WN∞) is a harder problem, being Π12-complete, and thereby strictly higher in the analytical hierarchy. We assume familiarity with infinitary term rewriting; we further reading we refer to [5,4]. 1 Infinitary Strong Normalization and Reachability Defi...

an important property of electromagnetic fields, which arises from the interaction between fields and chiral molecules, is called optical chirality. by enhancing this field property, while maintaining constant input power, we are able to increase absorption of circularly polarized light by chiral molecules of a certain handedness. this enhancement is achieved through the use of achiral plasmoni...

Introduction High frequency lateral tape motion (LTM) is a problem in tape technology that limits track density in a tape drive. To reduce high frequency LTM, it is important to identify all sources of lateral tape motion. The most important sources of high frequency LTM are edge contact between tape and tape drive components, non-repeatable roller axial run-out, air induced flutter and tape te...

Today large amounts of data are stored on tertiary storage media such as magnetic tapes and optical disks. DBMSs typically operate only on magnetic disks since they know how to maneuver disks and how to optimize accesses on them. Tertiary devices present a problem for DBMSs since these devices have dismountable media and have very diier-ent operational characteristics compared to magnetic disks...

Heat transfer by flame jet impingement is widely used in many of the industrial and domestic applications like heating metal bars, scrap melting, shaping glass, slab cutting, cooking others. Aim present experimental work to study an effect swirl on a local heat flux distribution inverse diffusion (IDF) impinging flat target surface coaxial tube burner. The twisted tape twist ratio 3 (correspond...
