Torque and power characteristics of a helium charged Stirling engine with a lever controlled displacer driving mechanism

Numerical characterization of a γ-Stirling engine considering losses and interaction between functioning parameters

“…power increases with the initial filling pressure and with the cooling water flow rates. This affirmation is concluded by Karabulut et al [10] too. The charge pressure has positive effect on the Stirling engine performances up to a limit value after which it becomes negative.…”

Connectionist intelligent model estimates output power and torque of stirling engine

“…Karabulut et al investigated the stirling engine which used helium as the working fluid with a lever-adjusted displacer driving mechanism [7]. The results of his study confirmed that the maximum torque and power are 3.99 Nm and 183 W at 4 bars pressure of charge and 533 K temperature of hot side.…”

“…A point to consider is that the improved SVM procedure, [46] profits from the pros of the earlier version of the approach as well. The regression deviation of the LSSVM [46] model is identified as the difference between the estimated characteristic and measured values, [50][51][52][53][54][55][56][57][58] that is noticed as an extension to the limitation of the optimization quandary. In conventional SVM model, the regression errors are commonly optimized in the calculations; however, in the LSSVM, [46] the deviation is mathematically determined [40,[46][47][48][49][74][75][76][77][78].…”

“…and exp denote the estimated, and measured one (power and torque) values, [50][51][52][53][54][55][56][57][58] correspondingly, and ns represents the samples' number from the primary population. In the present investigation, the LSSVM [46] model is employed.…”

Using GMDH Neural Networks to Model the Power and Torque of a Stirling Engine

“…Sripakagorn and Srikam [6] built a beta-type Stirling engine that operated at a medium temperature range and generated 95.4 W of electric power with internal conditions of 773 K and 7 bar. Karabulut et al [7] built a Stirling engine capable of generating 183 W of electric power using a working fluid of helium that attains a pressure of 4 bar. Cheng and Yu [8] investigated numerically a beta-type Stirling engine to identify the effects of various parameters, including non-isothermal effects and the performance of the regenerative channel.…”
