Face Grinding

The paper proposes a methodology for experimental studies of double-sided face grinding machines on the criterion of heat resistance, including: method of simulating a grinding process; measurement of temperature; measurement of changes in relative angular position of the circles; the measurement of processing errors. The proposed methods for experimental studies of the thermal behavior and errors in the machining of a double-sided face grinder allow for fine-tuning of the machine under production conditions. At the same time, preliminary tests of a double-sided face grinder show that when grinding an industrial batch of cylindrical rollers, excessive temperatures are distributed unevenly across the machine nodes both at idle and during grinding. The ends of the spindle heads and the stand have the greatest excess temperature when working at idle, and when grinding - on the surface of the machine, located in close proximity to the grinding zone. The nature of changes in excess temperatures of characteristic points and coolant when simulating the grinding process on the machine completely coincided with the experimental data obtained on a working machine.

The current study experimentally investigates the heat transfer augmentation on the novel axial corrugated heat exchanger tube in which the spring tape is introduced. Air (Pr = 0.707) is used as a working fluid. In order to augment the thermohydraulic performance, a corrugated tube with inserts is offered. The experimental study is further extended by varying the important parameters like spring ratio (y = 1.5, 2.0, 2.5) and Reynolds number (Re = 10 000–52 000). The angular pitch between the two neighboring corrugations and the angle of the corrugation is kept constant through the experiments at β = 1200 and α = 600 respectively, while two different corrugations heights (h) are analyzed. While increasing the corrugation height and decreasing the spring ratio, the impact of the swirling effect improves the thermal performance of the system. The maximum thermal performance is obtained when the corrugation height is h = 0.2 and spring ratio y = 1.5. Eventually, correlations for predicting friction factor (f) and Nusselt number (Nu) are developed.
