History of the stirling engine

The goal is to find out the relationship between the rhombic drive mechanism parameters and the performance of a low-temperature differential Stirling engine. In parallel, semi-free piston Stirling engine generators have been experimentally studied as one of the candidate converters for future space power generation. In fact, reducing environmental impacts of conventional energy resources and meeting the growing energy demand of the global population had motivated considerable research attention in a wide range of environmental and engineering application of renewable form of energy [ 4 ], and among all possible alternative energy options, solar energy is becoming more popular in the world. In this optic, this paper aims to study the drive mechanism adopted in the studied machine, which is the rhombic drive mechanism. These characteristics make the Stirling engines adapted to the demand of the effective use of energy and environmental preservation [ 2 , 3 ]. Measurements with flat plate cooler and discontinuous motion of the displacer were conducted to verify some recommendations of Kolin in expectation of power output improvement. The former work is focused on developing a high efficiency solar receiver for future space energy experiments on the Japan Experiment Module-Exposed Facility of the International Space Station. Thus, a parametric study based on Schmidt theory is conducted to find out the relationship between the rhombic drive parameters and the performance of low-temperature Stirling engines. The research work involves both a solar receiver and Stirling power generation technologies. This engine is known by high heat conversion efficiency, reliability, low noise operation, and ability to use many fuels. Moreover, as the relationship between rhombic drive mechanism parameters is not enough studied and available for researchers, a study of these parameters is conducted, and a methodology of choosing their values is suggested. Therefore, a special attention should be kept for each construction parameter in order to optimize the machine performance.

This is mainly due to the availability of plenty of sunlight in many countries [ 5 ]. Based on these achievements, the design work for an improved Stirling generator system is underway.

It is composed of a cavity receiver, thermal energy storage and sodium heat pipes, and aims at transporting solar heat to a bottoming system with the minimized heat loss. A ground test model of the solar receiver will be experimentally evaluated in NAL. Thus, a parametric study based on Schmidt theory is conducted to find out the relationship between the rhombic drive parameters and the performance of low-temperature Stirling engines. This engine was tested and studied under real conditions [ 11 ]. In , Martaj et al. The goal is to find out the relationship between the rhombic drive mechanism parameters and the performance of a low-temperature differential Stirling engine. This new prototype is designed to be simple, robust, cheap, and stable to be used for water pumping in poor rural African areas.

They presented several experimental measurements made under laboratory and field-test conditions in Morocco [ 11 ]. A ground test model of the solar receiver will be experimentally evaluated in NAL.

This new prototype is designed to be simple, robust, cheap, and stable to be used for water pumping in poor rural African areas. They concluded that the assumption of Kolin related to the proportionality of speed to temperature difference is justified, but the expectation about improvement of the machine performance with discontinuous motion of the two pistons needs to be reviewed.

In parallel, semi-free piston Stirling engine generators have been experimentally studied as one of the candidate converters for future space power generation. The goal is to find out the relationship between the rhombic drive mechanism parameters and the performance of a low-temperature differential Stirling engine. Background The Stirling engine is an externally heated machine which runs according to a reversible closed cycle. It was invented in by the Stirling brothers [ 1 ]. Besides, it is a solar engine, fact that lowers significantly its use price. This engine is known by high heat conversion efficiency, reliability, low noise operation, and ability to use many fuels. A thermodynamic analysis of the prototype is also conducted. The results indicate that the offset distance from the gear center and gear radius of the rhombic drive mechanism have to be maximized, in order to increase the indicated power, while other rhombic drive parameters should be reduced for the same reason. These characteristics make the Stirling engines adapted to the demand of the effective use of energy and environmental preservation [ 2 , 3 ]. Resources and Help Experimental study on Stirling engine generator and solar receiver system for future space applications Abstract: A fundamental study on solar Stirling power generation system has been performed as a part of the space solar power technology program in National Aerospace Laboratory NAL. Another result is that for realizing the optimized phase angle for beta-type Stirling engines, one should act on working piston-related bars and rhombic drive gear radius. In this optic, this paper aims to study the drive mechanism adopted in the studied machine, which is the rhombic drive mechanism. Based on the conclusions of this study, a new prototype of LTD-SE with rhombic drive mechanism is being developed.

Since this machine is developed to be as low expensive as possible, it was designed without any concentrator mechanism; consequently, its power output is relatively low. These characteristics make the Stirling engines adapted to the demand of the effective use of energy and environmental preservation [ 23 ].

In fact, reducing environmental impacts of conventional energy resources and meeting the growing energy demand of the global population had motivated considerable research attention in a wide range of environmental and engineering application of renewable form of energy [ 4 ], and among all possible alternative energy options, solar energy is becoming more popular in the world.
