A Micro-Thermal Photovoltaic (MTPV) system with a Tesla-shaped micro combustor is proposed and studied to enhance thermal performance, electrical power output, energy efficiency, acoustic performance. The present study focuses on three key parameters: (1) inlet velocity, (2) equivalence ratio, (3) combustion channel dimensions. We introduce novel method analyze the performance of MTPV by integrating combustion, heat transfer, space radiation diffusion, photovoltaic effect numerically. Additionally, prevent blow-off in combustor, we incorporate Tesla valve-shaped design. reverse direct flow configuration shown lead better efficiency compared forward configuration. Furthermore, optimal output are achieved under stoichiometric conditions. Under 6 m/s, an inner diameter (D8) 2 mm reaches 8.36 %, surpassing that D8 8 2.36 %. This highlights positive impact increasing varying both efficiency. transmission loss initially experiences increase followed subsequent decrease flow. In contrast, flow, higher 44.68 dB 18.85 specifically at 20 Hz 4500 Hz. Consequently, notably superior particularly high frequencies low frequencies.

A novel micro-mixing micro-combustor was developed and the flame stabilization characteristics were investigated numerically. The Combustor exhibited excellent lean stability limits, with limits increasing as fuel-air mixture became leaner. Stability achieved for equivalence ratios 1.0, 0.8 0.6 8m/s, 14m/s 16m/s respectively (although exact blow-off limit each case is expected to be higher). are higher than those reported in previous studies of hydrogen fueled combustors. Numerical simulations conducted starting at a low velocity 2 m/s, an increase m/s up maximum 16 m/s. As Reynolds number exceeded 500 (Re > 500), above 6 performed using turbulent model account transition turbulence. An all-new criterion predict suggested by specifying range local ratio central slot interface (φinter) 7 ≤ φinter 21 (cold flow) both laminar regimes when φg 1.0. In regime, = 0.6, diffusion observed remain attached bluff body tip, while premixed present fuel stream due high burning hydrogen. uniformity wall temperature demonstrated significant improvement regimes, which crucial practical applications such thermoelectric generators (TEGs) similar systems. Furthermore, introduction resulted transformation into partially flame. underlying mechanisms driving this structure analyzed discussed detail. Regarding enhancement firing rates existing combustors compared that combustor results revealed 28% hike lift-off condition, would even determined.
