Análise térmica de um trocador de calor duplo tubo para resfriamento de um óleo e simulação do projeto mecânico inicial utilizando o suplemento flow simulation do solidworks 2016

Abstract

Faced with the current trend of improvement in the process industry as a way to develop production means that excel by the quality allied to an affordable cost, the requirement for increasingly efficient equipment becomes increasing. In this perspective, engineering is challenged to develop projects of excellence combining quality and minimization of costs to deliver equipment with high cost-benefit to society. In this sense, this project discusses the dimensioning of a double-tube type heat exchanger for the ISO VG 46 oil cooling process. The design is justified by the need to maintain the hydraulic fluid, ISO VG 46, under the normal conditions of specified by the manufacturer, thus ensuring a longer service life of the hydraulic components. After the design, the ideal heat exchanger was modeled in SOLID WORKS software and then simulations were performed to observe the behavior of the fluids inside the exchanger. Five simulations were performed varying the working pressures; soon after, thermal transfer, fluid temperature, velocity and pressure loss were analyzed, and it was concluded that the heat exchanger and the heat pump will meet the design constraints under a pressure of approximately 1,5 MPa. In this way, the designed exchanger meets the operating conditions provided by the manufacturer, with full conditions to keep the oil viscosity at 20 cSt, thus complying with the established working conditions. The interest in studying and analyzing heat exchangers was due to its wide use in several areas of industry, in production processes, chemical processes, air conditioning systems, electrical and electronic components, among others; showing in this way, the importance of obtaining an exchanger with a high competitive advantage
