Course Description and Objectives

The objective of this course is to present the fundamental principles of heat transfer by relating those principles to practical engineering applications.

The course will start from the introduction to heat transfer by conduction, radiation and convection, and cover the topics on steady-state analysis of heat transfer, unsteady-state heat transfer, numerical solution of heat conduction problems, practical problems for forced-convection heat transfer, and natural convection systems.

Students will learn the ability to solve heat-transfer problems often appeared in the area of environment and energy engineering.

Note: Course textbook is "Heat Transfer (9th ed., J.P. Holman, 2001)" written in English, but lecture will be given in Japanese.

Textbook: J. P. Holman, Heat Transfer, 9th Edition. McGrawHill, 2001.

Expected Course Outcome

Students achieving passing grades in this course will be able to do basic calculations on heat-transfer problems for environment and energy engineering. By the end of this course they should be able to:

(1) Understand the basic concepts of conduction, convection and radiation heat transfer.

(2) Understand how to formulate and solve one and two dimensionalconduction heat transfer problems. Solution techniques will include both analytical and numerical methods. Convection effects will be included as boundary conditions.

(3) Understand the fundamentals of the relationship between fluid flow and convection heat transfer.

(4) Apply empirical correlations for both forced and free convection to determine values for the convection heat transfer coefficient. Students will be able to calculate heat transfer rates using the coefficients.

(5) Understand the definitions and meanings of the dimensionless numbers(the Prandtl number, the Reynolds number, the Fourier number, the Biot number, the Nusselt number) and apply these numbers to engineering calculations.

Example of learning objectives

• Design of Heat Exchanger (熱交換器の設計)– Fluid enters into a tube at the temperature of 10℃ and the rate

of 100 L/min. (温度10℃の流体が100L/minのレートでチューブ内に入る) We want to get the fluid temperature of 40℃ at the outlet of the heat exchanger. (出口からの流出する流体の温度を40℃にしたい)

– Find the minimum length of the tube.(長さはどのくらい必要か?)

Course syllabus: FEN-SI3b41L3 Heat Transfer6

Prerequisites (授業履修に必要な知識)

Fundamental knowledge on fluid mechanics [Fluid Mechanics A (03-810070)] is necessary for understanding heat convection in flow streams.流れにおける対流熱伝達を理解するためには,流体力学に関する基礎知識が必要。2年時に『流体力学A』を履修していれば問題ない。

但し,講義を聞いて理解できれば問題はない

Students should be familiar with MS Excel because it will be often used for analytical and numerical calculations. MATLAB can be used for these calculations.解析解・数値解を求める計算では,エクセルシートを頻繁に使うので,その操作方法に慣れている必要がある。これらの計算では,MATLABを使うこともできる。
