Abstract: | Tujuan penelitian ini yaitu (1) Menganalisi distribusi temperatur pada heater mesin stirling dengan variasi bahan (Stainless steel 304, tembaga, aluminium, besi) (2) Mengevaluasi pengaruh ketebalan dinding heater (2.5mm hingga 12.5mm) terhadap distribusi temperatur, dan (3) Menentukan kombinasi bahan dan ketebalan dinding heater yang memberikan performa terbaik. Metode yang digunakan ialah metode simulasi numerik. Bahan yang digunakan adalah menggunakan gambaran tentang heater pada stirling engine tipe mCHPSE-012021. Penelitian menggunakan alat yaitu laptop HP dengan processor Ryzen 7 dan aplikasi yang digunakan adalah Solidworks 2023 dan Ansys Mechanical APDL.. Hasil penelitian ini ialah (1) gradien temperatur dengan ketebalan 5mm dengan variasi bahan yaitu stainless steel 304 (16.2W/m.K), tembaga (398W/m.K), aluminium (210W/m.K), dan besi (76.2W/m.K) adalah 3.684°C, 0.153°C, 0.29°C, 0.795°C, Terlihat bahwa bahan-bahan dengan konduktivitas termal yang lebih tinggi memiliki gradien suhu yang lebih kecil, yang menunjukkan bahwa bahan dengan konduktivitas termal tinggi memiliki transfer panas yang lebih efisien. (2) gradien temperatur dengan bahan stainless steel 304 dengan ketebalan 2.5mm, 5mm, 7.5mm, 10mm, dan 12.5mm adalah 0.141°C, 0.29°C, 0.474°C, 0.697°C, dan 0.922°C, menunjukkan bahwa semakin tebal dinding heater, semakin besar gradien temperatur yang terjadi. Hal ini disebabkan oleh peningkatan hambatan termal yang mengurangi efisiensi transfer panas dari pemanas ke fluida kerja. The objectives of this study are (1) To analyze the temperature distribution in the Stirling engine heater with various materials (Stainless steel 304, copper, aluminum, iron) (2) To evaluate the effect of heater wall thickness (2.5mm to 12.5mm) on temperature distribution, and (3) To determine the combination of materials and heater wall thickness that provide the best performance. The method used is a numerical simulation method. The material used is a description of the heater in the Stirling engine type mCHPSE-012021. The research used a tool, namely an HP laptop with a Ryzen 7 processor and the applications used were Solidworks 2023 and Ansys Mechanical APDL. The results of this study are (1) the temperature gradient with a thickness of 5mm with a variety of materials, namely stainless steel 304 (16.2W/m.K), copper (398W/m.K), aluminum (210W/m.K), and iron (76.2W/m.K) is 3,684°C, 0.153°C, 0.29°C, 0.795°C, It can be seen that materials with higher thermal conductivity have a smaller temperature gradient, which indicates that materials with high thermal conductivity have more efficient heat transfer. (2) The temperature gradients with 304 stainless steel material with thicknesses of 2.5mm, 5mm, 7.5mm, 10mm, and 12.5mm are 0.141°C, 0.29°C, 0.474°C, 0.697°C, and 0.922°C, respectively, indicating that the thicker the heater wall, the greater the temperature gradient that occurs. This is due to the increase in thermal resistance which reduces the efficiency of heat transfer from the heater to the working fluid. |
