OVERVIEW

The course aims to provide the basic knowledge necessary for the understanding of the main physical phenomena interesting the yacht design: hinting at the energy systems thermodynamics, in particular, the study of heat transfer and lighting is approached.

AIMS AND CONTENT

LEARNING OUTCOMES

The aim of the course is the training of a person able to analyze and solve simple problems in different fields of applied physics, while helping to acquire a proper scientific-technical language.

AIMS AND LEARNING OUTCOMES

The aim of the course is the training of a person able to solve simple math problems of thermodynamics and heat transfer, while helping to acquire a proper scientific-technical language, as an essential tool either to understand technical documentation or to talk with several actors in the designing and manufacturing processes of the pleasure boats.
Preliminary and essential to the study of physical phenomena is the familiarity with the physical dimensions of the mechanics and the relative units of measurement: the same are recalled in fact in the introductory part of the course.
The course then addresses the main topics of technical thermodynamics, hinting at the analysis of thermodynamic systems and energy exchanges that characterize them.
Following is the study of the main mechanisms of heat exchange, conduction, convection and thermal radiation. Finally, the main photometric quantities are introduced, with notes on colorimetry. Then the different types and the technical parameters of light sources and luminaires are analyzed.
With the aim of favoring an adequate critical knowledge of the phenomena, numerical exercises are also provided for the resolution of simple problems.

PREREQUISITES

The following basic mathematical knowledge is necessary to effectively address the teaching content.

• Calculation of areas and volumes of simple geometries.
• Functions: line, module, parabola, hyperbola, logarithm, exponential, trigonometric functions (sine, cosine, tangent and related inverse functions).
• Resolution of equations and of first and second degree, of equations with logarithms and trigonometric functions.
• Simple inequations.
• Meaning of limit.
• Differential calculus of a real variable: geometric interpretation of the concept of derivative and integral, calculation of derivatives and primitives of simple functions.
• Ordinary differential equations to the separable variables of the first and second order.

In order to face the resolution of simple numerical problems, it is also necessary to have an adequate familiarity in the use of a scientific calculator.

TEACHING METHODS

Teaching is carried out by alternating theoretical lessons with practical/numerical exercises.

SYLLABUS/CONTENT

The main topics discussed are the following.

GENERAL PHYSICS RECALLS: mechanics, static of fluids, notes of electricity.

NOTES ON TECHNICAL THERMODYNAMICS: closed and open thermodynamic systems, temperature, heat, mechanical work, first and second principle of thermodynamics, dynamics of fluids.

HEAT TRANSFER: conduction, convection, thermal radiation, combined heat transfer mechanisms.

LIGHTING: physical nature of light, light emission by temperature and luminescence; photometry and photometric dimensions; notes on colorimetry; types and technical parameters of light sources and luminaires.
