In the last few years, we have witnessed significant progress in developing high performance shape memory polymer (SMP) nanocomposites, in particular, for shape recovery activated by indirect heating in the presence of electricity, magnetism, light, radio frequency, microwave and radiation, etc. In this paper, we critically review recent findings in Joule heating of SMP nanocomposites incorpora...

Near-field electromagnetic heat transfer is of interest for a variety of applications, including energy conversion, and precision heating, cooling and imaging of nanostructures. This past decade has seen considerable progress in the study of near-field electromagnetic heat transfer, but it is only very recently that numerically exact methods have been developed for treating near-field heat tran...

Induction heating process was investigated numerically and experimentally. Cylindrically shaped steel workpiece was heated with different heating protocols. Numerical model with coupled electromagnetic and thermal physical phenomena was solved using the finite element method. Temperature-dependent and temperature-independent steel material properties were considered and their impact on simulati...

EOAF 12004160 65 66 67 68 69 70 71 Abstract Fiber-optic sensors do not interfere with electromagnetic fields and are commonly used to measure temperature and pressure used in microwave and frequency heating research and applications. This article introduces the physical principles for three different types of commonly used fiber-optic sensors and discusses important parameters to be considered ...

Based on the electromagnetic induction heating method, and curing of Carbon Fiber Reinforced Polymer (CFRP) have advantages high energy utilization no pollution. However, in process, both material weaving structure mold can affect temperature field. Therefore, this study, an finite element analysis model for CFRP circular tubes was established based equivalent thermal characteristics CFRP. The ...

The invasive Red Palm Weevil is the major pest of palms. Several control methods have been applied, however concern is raised regarding the treatments that can cause significant environmental pollution. In this context the use of microwaves is particularly attractive. Microwave heating applications are increasingly proposed in the management of a wide range of agricultural and wood pests, explo...

The first demonstration of electron-Bernstein-wave heating by double-mode conversion from the O to the X mode in an overdense H-mode tokamak plasma has been achieved in the Tokamak à Configuration Variable device. This technique overcomes the upper density limit experienced by conventional microwave heating. The sensitive dependence of the O-X mode conversion on the microwave launching directio...

A reduced order model based on a two-time scale separation of the solution of a PDE is developed for the heating of food products with microwaves. This approach is employed on a Model Predictive Control framework to achieve uniformity of different quality parameters. Due to the fact that predictive control requires measurements which are not always possible to obtain, observers were constructed...

Bulk quantities of nanocarbons having pre-selected morphology can be synthesized in a simple and rapid microwave heating approach directly from conducting polymers.
