This in particular applies for manufacturing processes like milling, drilling and turning for high-value turbomachinery components like impellers, combustion engines and compressors of the aerospace and automotive industry as well as energy generation, which play a major role in modern societies. However, numerous analytical and experimental efforts have been conducted in order to understand the thermal conditions in metal cutting, yet many questions still prevail. Most models are based on a stationary point of view and do not include time dependent effects like in intensity and distribution varying heat sources, varying engagement conditions and progressive tool wear. In order to cover such transient physics an analytical approach based on Green's functions for the solution of the partial differential equations of unsteady heat conduction in solids is used to model entire transient temperature fields. The validation of the model is carried out in orthogonal cutting experiments not only punctually but also for entire temperature fields. For these experiments an integrated measurement of prevailing cutting force and temperature fields in the tool and the chip by means of high-speed thermography were applied. The thermal images were analyzed with regard to thermodynamic energy balancing in order to derive the heat partition between tool, chips and workpiece. The thus calculated heat flow into the tool was subsequently used in order to analytically model the transient volumetric temperature fields in the tool. The described methodology enables the modeling of the transient thermal state in the cutting zone and particular in the tool, which is directly linked to phenomena like tool wear and workpiece surface modifications.}, language = {en} } @article{ausderWiesche2012, author = {aus der Wiesche, Stefan}, title = {A Mobile Test Rig for Micro Gas Turbines Based on a Thermal Power Measurement Approach}, series = {ASME Journal for Engineering of Gas Turbines and Power}, volume = {134}, journal = {ASME Journal for Engineering of Gas Turbines and Power}, doi = {10.1115/1.4007201}, year = {2012}, language = {en} } @article{ausderWiesche2020, author = {aus der Wiesche, Stefan}, title = {Stagnation Flow and Heat Transfer From a Finite Disk Situated Perpendicular to a Uniform Stream}, series = {ASME Journal of Fluids Engineering}, volume = {142}, journal = {ASME Journal of Fluids Engineering}, number = {3}, pages = {031108 (15 pages)}, year = {2020}, language = {en} } @article{ausderWiesche2007, author = {aus der Wiesche, Stefan}, title = {The Cauchy surface wave problem from the viewpoint of a VOF method}, series = {Computational Mechanics}, journal = {Computational Mechanics}, pages = {141 -- 152}, year = {2007}, language = {en} } @article{ausderWiesche2007, author = {aus der Wiesche, Stefan}, title = {Heat transfer from a rotating disk in a parallel air crossflow}, series = {International Journal of Thermal Science}, journal = {International Journal of Thermal Science}, pages = {745 -- 754}, year = {2007}, language = {en} } @article{ausderWiesche2007, author = {aus der Wiesche, Stefan}, title = {Large-eddy-simulation study of an air flow past a heated square cylinder}, series = {Heat and Mass Transfer}, journal = {Heat and Mass Transfer}, pages = {515 -- 525}, year = {2007}, language = {en} }
