Objetivos
This curricular unit aims that students should: Acquire basic knowledge about transport of momentum and heat; Apply the knowledge acquired in solving problems involving fluid flow and heat transfer; Know how to establishing balance sheets of thermal energy and boundary conditions. After approval students should have the ability to: Design transport systems of a fluid. Understand the fundamentals of energy transfer, being able to apply it for solving practical problems. Identify the processes involved in heat transfer to calculate the amount of heat transferred in one-dimensional systems, using a second Fourier's law, determine the temperature profile and the amount of heat transferred in one-dimensional systems involving heat generation; Analysis of heat transfer equipment, being able to apply knowledge acquired to the selection and design of heat exchangers. Select and design isolation.
