AB  - Bu çalışmanın amacı, bir Vanasız Serbest Piston Lineer Genleştirici’nin (SPLG) uzun süreli sürekli rejim çalışmasını elde etmektir. Giriş ve çıkış sıcaklıklarını, giriş ve çıkış basınçlarını, debiyi ve voltaj çıktısını ölçmek için bir deneysel test düzeneği kuruldu. Frekans, voltaj ortalama karekök değeri, hacimsel verim, elektrik-mekanik dönüşüm verimi, izantropik verim, tersinmezlik, gerçek genleştirici işi ve elektrik gücü gibi birçok çıktı parametrelerinin eğilimleri sunuldu. SPLG’nin bu ilk çalışmasında, 44 Hz maksimum genleştirici frekansı ve %21,5 maksimum izantropik verim elde edildi.

N2  - The objective of this work was to achieve long-term steady state operation of a Valveless Free-Piston Linear Expander (FPLE). An experimental test bench was developed to measure the inlet and outlet temperatures, inlet and outlet pressures, flow rate, and voltage output. The trends of several output parameters such as frequency, average root mean square (RMS) voltage, volumetric efficiency, electrical-mechanical conversion efficiency, isentropic efficiency, irreversibility, actual expander work, and electrical power were presented. This first iteration FPLE achieved a maximum expander frequency of 44 Hz and a maximum isentropic efficiency of 21.5%.
