Multi-Objective Matched Synchrosqueezing Chirplet Transform for Fault Feature Extraction From Marine Turbochargers

open access: yesIEEE Access, 2023
Turbocharger is one of the vital parts of a diesel engine causing a high failure rate. Its surface vibration signal contains important time-varying features.

A comparative study on mean value modelling of two-stroke marine diesel engine [PDF]

open access: yes, 2009
In the present paper, two mean value modelling approaches of varying complexity, capable of simulating two-stroke marine Diesel engines, are presented. Both approaches were implemented in the computational environment of MATLAB Simulink®. Simulation runs

Tutorial Overview: Numerical Synergy in Muffler Acoustic Design A Critical Comparison of TMM, FEM, and CFD Approaches for Transmission Loss Quantification

open access: yesEngineering Reports, Volume 8, Issue 1, January 2026.
Experimental measurements reveal distinct performance boundaries: TMM achieves rapid convergence (< 2 dB error below 2000 Hz) but neglects 3D wave effects; FEA maintains < 10% deviation up to 3500 Hz with 90% reduced computational cost versus CFD; while transient CFD captures broadband attenuation trends despite 10× higher resource demands.

A machine‐learning interatomic potential for Si‐C‐N‐H with application to polymer‐to‐ceramic processing of polysilazanes

open access: yesJournal of the American Ceramic Society, Volume 109, Issue 1, January 2026.
Abstract We developed a machine‐learning interatomic potential (MLIP) based on Moment Tensor Potentials for atomistic simulations in the Si‐C‐N‐H system. The MLIP was trained on ordered and disordered configurations—including crystalline phases, polymers, amorphous models, and high‐temperature ab initio molecular dynamics trajectories of chemical ...

Characterization of Thin Walled Ti-6Al-4V Components Reduced via Electron Beam Melting [PDF]

open access: yes, 2004
Direct-metal energy beam SFF processes typically produce layers by scanning the contours and then filling in the area within the contour. Process parameters used to solidify contours are often different from those for fill areas.

Performance Evaluation of a Naturally Aspirated Diesel Engine With High n‐Pentanol–Diesel Blends Under Full‐Load Conditions

open access: yesInternational Journal of Energy Research, Volume 2026, Issue 1, 2026.
This study investigates the effects of n‐pentanol/diesel blends on the performance of a naturally aspirated, air‐cooled, single‐cylinder diesel engine under full load across 1400–2500 rpm. The engine was equipped with a mechanical direct injection system.

X‐Ray Computed Tomography Quantifies Primary Phases and Reveals Crack Morphology in High‐Cycle Fatigue of Aluminum Alloy EN AW‐2618A

open access: yesAdvanced Engineering Materials, Volume 27, Issue 24, December 2025.
Primary phases and a fatigue crack are studied in a forged blank of an aluminum alloy using synchrotron and laboratory X‐ray computed tomography. To image the crack, the fatigue test is interrupted, and a static tensile load is applied to open the crack.

Comparison study between two types of nozzles for a turbocharger balancing machine using ANSYS software [PDF]

open access: yesMATEC Web of Conferences, 2019
Turbocharger balancing machines require a specific tooling for spinning the center housing rotating assembly, in order to balance it dynamically. The tooling requires a nozzle to guide the air to the blades of the turbine wheel in order to spin it ...
