Zone Temperature

High temperature in grinding can cause thermal damage to the workpiece. In order to reduce the grinding zone temperature, a method about enhancing heat transfer based on the rotation heat pipe technology is proposed. In this paper, the heat transfer effect of heat pipe grinding wheel (HPGW) under different conditions such as the rotating speed of grinding wheel, the kinds of working fluid and the film thickness are analyzed. The results show that the HPGW has great superiority of heat transfer under certain conditions.

Experimental study was carried out with TiO2 Nano-sized compounds coated on aluminum foil to study the cleaning properties and heat transfer effect. The experiments were also carried out for air conditioners which fins of evaporator and condenser were coated with TiO2 nano compound coating. Results show that the foils with TiO2 nano compound coating presents better self-cleaning property and improved heat transfer effect. Air conditioner’s properties with TiO2 nano compound coating evaporator and condenser is higher than that without coating. The maximum heat capacity was found to be increased 8%. The nano-sized liquid showed better synthetic function such as excellent hydrophilic, better cohesion, water flushing resistance.

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.
