Prompt-guided diffusion approach for deep generative vehicle designs under user-defined specifications

Published on 2026-06-24 by @OXFORD

Abstract: AbstractEngineering vehicle design presents significant challenges due to its resource-intensive nature and the need to satisfy diverse design requirements. While recent data-driven generative models have shown promise, key limitations remain: (1) the difficulty of simultaneously addressing multiple design factors, such as user intent and engineering validity, and (2) the lack of accessibility and user-friendliness for intuitive design exploration. To overcome these challenges, this study introd[...]


Our summary: This study presents a prompt-guided diffusion framework for generating high-fidelity vehicle designs. It addresses challenges in engineering design by integrating user-defined specifications with generative models. Evaluations show significant improvements in design quality and generalization under data-scarce conditions.

CFD-based analysis of chimney performance optimization for the Manzanares pilot plant

Published on 2026-03-19 by @OXFORD

Abstract: AbstractThis research conducts an extensive computational fluid dynamics (CFD) analysis aimed at optimizing the geometric configuration of solar chimney power plants (SCPPs), with particular emphasis on the Manzanares pilot plant. The research analyses the effects of chimney diameter and divergent chimney design on system performance under steady-state conditions at 1000 W/m2 solar irradiance and 300 K ambient temperature. A validated three-dimensional CFD model with a 90° symmetry sector is [...]


Our summary: This research utilizes CFD to optimize chimney design for the Manzanares pilot plant. The study finds that increasing chimney diameter significantly boosts power output, while a divergent configuration further enhances performance. Optimal design parameters lead to substantial improvements in airflow and energy generation, providing a cost-effective solution for future installations.
