An inverse method to estimate the moving heat source in machining process
(PERGAMON-ELSEVIER SCIENCE LTDOXFORD, 2012)
The present work propounds an inverse method to estimate the heat sources in the transient two-dimensional heat conduction problem in a rectangular domain with convective bounders. The non homogeneous partial differential ...
Contribution to dynamic characteristics of the cutting temperature in the drilling process considering one dimension heat flow
(PERGAMON-ELSEVIER SCIENCE LTD, 2011)
The machining of hardened steels has always been a great challenge in metal cutting, particularly for drilling operations. Generally, drilling is the machining process that is most difficult to cool due to the tool`s ...
Analysis of reverse heat transfer for conventional and optimized lubri-cooling methods during tangential surface grinding of ABNT 1020 steel
(Fundação Gorceix, 2016-12-01)
Abstract A numerical thermal model was developed to evaluate the heat flux which is conducted to a rectangular workpiece of steel plate ABNT 1020, thus making it possible to compute the maximum temperature in the grinding ...
Experimental Determination of Surface Heat Transfer Coefficient in a Dry Ice-ethanol Cooling Bath Using a Numerical Approach
(Cryo Letters, 2017-03)
Dry ice-ethanol bath (-78ºC) have been widely used in low temperature biological research to attain rapid cooling of samples below freezing temperature. The prediction of cooling rates of biological samples immersed in dry ...
