Numerical Investigation of Transonic Axial Compressor Rotor With Leading‐Edge Tubercles

open access: yesEngineering Reports, Volume 8, Issue 3, March 2026.
Amplitude, wavelength, and span‐wise location of the leading‐edge tubercles on a transonic NASA Rotor 37 compressor are numerically optimized. An increase in efficiency by 0.52% compared to the corresponding baseline rotor is observed. The location of the shockwave moves downstream of the rotor with 1.91% higher pressure.

Research on Precise Identification of Rock Strength Based on Bolt Drilling Parameters

open access: yesEnergy Science &Engineering, Volume 14, Issue 3, Page 1353-1371, March 2026.
Drilling detection test platform. ABSTRACT During roadway excavation, the presence of weak interlayers and fractured rock masses significantly affects roof stability. To achieve timely and effective roadway support, it is crucial to identify and predict different rock types based on drilling signals from roof bolters.

Experimental and Numerical Study on Enhancing the Performance of a Stepped Solar Still Using Porous Sponge Materials

open access: yesEnergy Science &Engineering, Volume 14, Issue 3, Page 1456-1473, March 2026.
Three designs were built and tested: a single‐slope still, a six‐stepped still, and a six‐stepped still with 5 mm sponge sheets. The novelty lies in fixing porous sponge sheets to the vertical faces of the steps. Yield of freshwater and instantaneous efficiency were determined in various combinations, that is, base, stepped, and stepped‐cum‐sponge ...

Biomechanical Analysis and Injury Prediction in Pilots With Lumbar Spondylolysis Under Different Seat Inclination Angles

open access: yesJOR SPINE, Volume 9, Issue 1, March 2026.
The biomechanical responses of three lumbar models under both seat angles remain below injury thresholds. However, the occurrence of spondylolysis at a 22° angle poses a higher risk. ABSTRACT Background This study aims to quantify the biomechanical effects of different seat inclinations on the normal and spondylolysis lumbar of pilots under typical ...
