Hemant Yadav
Abstract
This chapter deals from fundamentals to advanced aspects of transfer of heat in forced and natural convectionnatural convection mode by exploring both theoretical models and practical applications. Forced and natural convection play crucial roles in engineering field where efficient heat transfer is essential, such as in cooling systems, energy production as well as climate control. We begin by examining the governing principles of convection heat transferconvection heat transfer, highlighting the differences and interactions between forced and natural convection mechanisms. By a detailed analysis, key parameters such as fluid velocity, temperature gradientstemperature gradients, and surface properties that influence heat transfer rates will be explored.
To solve convection problems in complex geometries, computational techniquescomputational techniques like finite element and finite volume methodsfinite volume methods are used, which help to get optimized heat transfer performance in engineering applications. To demonstrate the practical significance of efficient convection heat transfer,convection heat transfer different case studies based on industries are also provided, such as in electronic device thermal managementthermal management, and HVAC systems. A combination of both theoretical insights and practical examples allow researchers and practitioners to enhance their understanding and application of heat transfer in forced and natural convectionnatural convection systems.
