Direct numerical simulation of heat transfer from the stagnation region of a heated cylinder affected by an impinging wake [PDF]
, 2011 Copyright © 2011 Cambridge University Press.The effect of an incoming wake on the flow around and heat transfer from the stagnation region of a circular cylinder was studied using direct numerical simulations (DNSs).

The use of pseudo-inertia in asymptotic modelling of constraints in boundary value problems [PDF]
, 2009 In recent publications, the validity of using positive and negative inertial penalty parameters and the advantage of this approach over the conventional positive penalty function approach have been established for linear eigenvalue problems.

Characteristics of Heat Transfer for Heat Pipe and Its Correlation [PDF]
ISRN Mechanical Engineering, 2011 In spite of wide application of heat pipe in microelectronics cooling system, a complete understanding of heat pipe mechanism has not yet been completed. An experimental investigation of heat transfer performance of a heat pipe for dry condition and with three different liquids as acetone, methanol, and water having four fill ratios, for each liquid ...

A heat pump at a molecular scale controlled by a mechanical force
, 2006 We show that a mesoscopic system such as Feynman's ratchet may operate as a heat pump, and clarify a underlying physical picture. We consider a system of a particle moving along an asymmetric periodic structure . When put into a contact with two distinct

Transient heat transfer characteristics of a heat pipe.
KAGAKU KOGAKU RONBUNSHU, 1987 Transient heat transfer characteristics of a typical heat pipe for which the thermal loading was variable with time were investigated experimentally by using an automatic measuring system. Significant behaviour of step, frequency and pulse responses of surface temperature and heat transferred in particular was observed.

Evaluation of Evaporative Heat Transfer Characteristics of Helmets.
APPLIED HUMAN SCIENCE Journal of Physiological Anthropology, 1997 The prime purpose of a safety helmet is to protect against occupational hazards. However, thermal comfort is one important ergonomics requirement for a helmet to be accepted by its wearer. To design and manufacture a thermally comfortable helmet, a method for testing and evaluating the thermal properties is essential.
