This paper presents a systematic procedure based on the adjoint method for solving a class of inverse directional alloy solidification design problems in which a desired growth velocity v f is achieved under stable growth conditions. To the best of our knowledge, this is the first time that a continuum adjoint formulation is proposed for the solution of an inverse problem with simultaneous heat...
In this paper the studies of the two-phase super Plasticity stainless steels is studied. The aim of this study obtained the suitable criteria to thermo-mechanical treatment condition for decrease the microstructure (grain size) and super plasticity property in two-phase stainless steels. Also here we want to show the appropriate ranges of temperature and strain rate used in the process super pl...
Temperature sensor using piezoelectric quartz tuning fork resonators have attracted much interest due to their simple structure and potentially high sensitivity. In this paper, we present the fundamental limits of the use of quartz tuning fork (QTF) for temperature sensor. The QTF temperature sensors are tuning fork quartz crystal vibrating in flexural model and optimally designed with a therma...
A general framework for the thermodynamics of open systems is presented. The theory is fundamentally based on the generalized balance of mass, which is enhanced by additional surface-°ux and volume-source terms. The presentation highlights the in°uence of the enhanced mass balance on the remaining balance equations. To clarify the impact of the variable reference density, we introduce the notio...
We demonstrate an ultrasensitive temperature sensor based on an isopropanol-sealed optical microfiber taper (OMT) in a capillary. The OMT is highly sensitive to ambient refractive index (RI) with a maximum sensitivity of 18989 nm/RI unit in the range of 1.3955-1.4008. The thermo-optic effect of isopropanol and the thermal expansions of the sealant and sealed liquid turn the OMT into an ultrasen...
