The present investigation is concerned with the propagation of waves at an imperfect boundary of heat conducting elastic solid and micropolar fluid media. The amplitude ratios of various reflected and transmitted waves are obtained in a closed form due to incidence of longitudinal wave (P-wave), thermal wave (T-wave), and transverse wave (SV-wave). The variation of various amplitude ratios with...

The operation of thermal diodes is typically limited to narrow temperature ranges and low rectification steady-state heat currents. Despite their key application in computing, the analogy electronic counterparts, development operating with modulated currents has not received much attention. Based on spatiotemporal modulation a material's conductivity volumetric capacity, authors give proof prin...

As an important way to control and manage heat transport, thermal rectification has become an elementary issue in the field of phononics and plays a key role in the designing of thermal devices. Here we investigate systematically the standing wave and the accompanying resonance process in asymmetric nanowires to understand the standing wave itself and its great effect on thermal rectification. ...

The fundamental solution of the system of differential equations in bio-thermoelasticity with dual phase lag (DPL) in case of steady oscillations in terms of elementary function is constructed and basic property is established. The tissue is considered as an isotropic medium and the propagation of plane harmonic waves is studied. The Christoffel equations are obtained and modified with the ther...

Recently, laser induced thermal wave based technologies have provided a powerful class of techniques for the evaluation of solid state materials [1,2). Through the use of tightly focussed optical beams modulated at high frequencies, it has been possible to both generate and interrogate highly localized thermal wave phenomena in materials with spatial resolutions approaching 1 J.1m [2]. The uniq...

Heat transfer enhancement technology has the aim of developing more efficient systems as demanded in many applications. An available passive method is represented by the employ of rough surfaces. Transversal turbulators enhance the heat transfer rate by reducing the thermal resistance near surfaces, because of the improved local turbulence; on the other hand, higher losses are expected. In this...
