OBSERVATION OF HEAT PUMPING EFFECT BY RADIATIVE SHUTTLING

Observation of heat pumping effect by radiative shuttling

Abstract Heat shuttling phenomenon is characterized by the presence of a non-zero heat flow between two bodies without net thermal bias on average.It was initially predicted in the context of nonlinear heat conduction within atomic lattices coupled to two time-oscillating thermostats.Recent theoretical works revealed an analog of this effect for Ba

Rail steel contact fatigue curves

Introduction.The problem of contact fatigue damage of rails has become especially urgent with the intensified railway freight load.An effective method of studying various damage factors is mathematical simulation of the dynamics of motion and accumulation of contact fatigue damage in the rail material.The damage accumulation simulation uses a curve

Evaluation of compressive and split tensile strength of slag based aluminosilicate geopolymer reinforced by waste polymeric materials using Taguchi method

In this work, slag based aluminosilicate geopolymer was reinforced with polymeric fibers including, polyester (PES) (waste tire cap plies), polymeric particles including polyethylene terephthalate (PET) (waste water bottle), styrene-butadiene rubber (SBR) (waste tire), and polyvinyl chloride (PVC) (waste water hose).The tensile and compressive stre
