Investigation of the effects on heating efficiency of flow parameters in induction fluid heater

Heating operation is located in the applications which are widely used in daily life and industry. In various industries as to ensure comfort conditions and to facilitate the processing of metals is utilized from these types of applications. From metal processing to fluid heating, electromagnetic induction heating has a wide application range. Induction air heating system is designed to meet the needs in hospital, greenhouse etc. other requirements that air-conditioned place, is new and innovative technology. In this thesis; thermodynamic analysis was performed to determine the energy performance of the induction air heating system. Minimizing heat losses and increasing thermal efficiency was aimed for the system which used air as a working fluid. First law of thermodynamic was used in the analysis. To determine the accuracy of the experimental findings, COMSOL and uncertainty analysis were consulted. It was obtained that with increasing outlet cross-section diameter and mass flow rate, the total energy loss and outlet temperture of air was decreased, the thermal efficiency was increased for the prototypes. Insulated case of prototypes was evaluated and increased efficiency of insulated prototypes was observed. Based on the findings, the highest thermal efficiency were obtained for insulated K-4 which has the highest cross sectional outlet diameter and flow rate (%95,49). Maximum air temperature (95,4oC) was obtained in experiments in which insulated K-3 prototype with the smallest exit sectional diameter and the lowest flow rate.
