Analysis and Optimization of Reducing Steady State Time for Heating Systems [PDF]
International Journal of Advanced Design and Manufacturing Technology, 2009 Present paper is a result of consideration in reducing steady-state time of heating systems. For this purpose one should study boundary condition of the system until steady state condition.

Advanced Engineering Materials, EarlyView.Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated

Advanced Engineering Materials, EarlyView.A combined finite element and phase‐field approach predicts the evolution of microstructure during the directional solidification of Ni‐based superalloys. The model reveals how withdrawal rate, temperature gradient, and wall thickness control the dendrite spacing, highlighting the strong effect of surface regions in thin sections where dendrite growth ...

Modelling Of The Thermal Behavior Of Walls And Floors In Contact With The Ground
, 2012 One of the most complex configuration to model in detail, both in the dynamic simulation of buildings and in the analytical quasi steady-state calculations, is the thermal dispersion through the walls and the floor in contact with the ground. The problem

A steady-state analysis of the ε-normalized sign-error least mean square (NSLMS) adaptive algorithm
, 2011 In this work, expressions are derived for the steady-state excess-mean-square error (EMSE) of the ε-normalized sign-error least mean square (NSLMS) adaptive algorithm for both cases of real- and complex-valued data.

Evaluating Energy Absorption Performance of Filled Lattice Structures
Advanced Engineering Materials, EarlyView.Maximum stress must be considered to robustly evaluate energy absorber designs. This approach was applied to compare all types of absorbers in a single Ashby diagram and determine the utility of filling lattice voids with a second material. High‐performance fillers can improve the performance of lattices that are limited by buckling or catastrophic ...

From steady-state and dynamic analysis to adaptive control of the CSTR reactor
, 2011 Simulation is the technical discipline which shows the behavior and reactions of any system on its model. Most processes in nature have nonlinear properties and simulation is one way to examine behaviour of these systems.

Advanced Engineering Materials, EarlyView.New features on yttria‐stabilized zirconia after exposure at 1500°C: Newly discovered pyramidal structures on an old material. After exposure at 1550°C on the cross section of YSZ new features, namely pyramidal structures are discovered. These structures grow with time, increase in numbers, appear as singularities, are often arranged in strings, and ...
