(or thermionic generator), a device for the direct conversion of thermal energy into electrical energy on the basis of the phenomenon of thermionic emission. The simplest type of thermionic converter consists of two electrodes separated by a vacuum gap (a simple cesium thermionic converter is shown in .

ROHSENOW HEAT AND MASS TRANSFER LABORATORY, MIT Thermionic Power.
Thermionic energy conversion is well suited for space applications. The conversion efficiency and high temperature of heat rejection minimize the size and weight of the radiator. Consequently, thermionic systems with high power-to-weight ratios are possible. In addition to the inherent. In thermionic emission, the heat supplies some electrons with at least the minimal energy required to overcome the attractive force holding them in the structure of the metal. This minimal energy, called the work function, is characteristic of the emitting material and the state of contamination of its surface. See also field emission.

Thermionic conversions is a method for converting heat directly into electrical energy. Unlike the conventional indirect methods for generating electricity from heat sources, no intermediate form of energy is required, and no working fluid – except the flow of the electrical charges themselves—are involved in the process.
And unlike other direct conversions methods, there is no need for. From Thermionic energy conversion book physical electronic viewpoint, thermionic energy conversion is the direct production of electric power from heat by thermionic electron emission. From a thermodynamic viewpoint, it is the use of electron vapor as the working fluid in a power-producing cycle.
The emphasis of the review is placed both on the available tools for the analysis of thermionic emission and on the problems that remain to be solved. Transport of low-energy particles through a vapor, of the type encountered in thermionic conversion, is discussed.

American Libraries. Uploaded by Kelly McDougall on November 3, SIMILAR ITEMS (based on metadata) Format: Ebook/DAISY Thermionic energy converters are well suited to a modular approach. Thermionics is a passive system without moving parts.
Thermionic energy conversion is able to use heat at the highest temperatures available, and to reject waste heat at temperatures high enough to be efficiently used bymore». Brief History of Thermionic Conversion T h e earliest known freelancerscomic.com thermionic energy conversion was given by Schlicter in (15).
He showed (neglecting space charge and assuming +a = c&) that the vacuum converter at maximum power output yields a current density of J at a voltage of kTc/e, where J is the zero-field cathode.
Thermionic conversion is a method for converting heat directly into electrical energy. Unlike the conventional indirect methods for generating electricity from heat sources, no intermediate form of energy is required, and no working fluid-except the flow of the electrical charges themselves-are involved in.
Thermionic emission is the liberation of electrons from an electrode by virtue of its temperature (releasing of energy supplied by heat).
This occurs because the thermal energy given to the carrier overcomes the work function of the material. The charge carriers can be electrons or ions, and in older literature are sometimes referred to as thermions.
Thermionic power converter, any of a class of devices that convert heat directly into electricity using thermionic emission rather than first changing it to some other form of energy. A thermionic power converter has two electrodes. One of these is raised to a sufficiently high temperature to. Dec 03, · Through a process known as thermionic conversion, heat energy—such as light from the sun or heat from burned fossil fuels—can be converted.
