An Experimental Investigation Of The Effect Of The Velocity Ratio On The Flow And Wall Heat Transfer Characteristics Of A Wall-Bounded Dual Jet, Paula J. Murphy, Sajad Alimohammadi, Séamus M. O'Shaughnessy Jan 2025

An Experimental Investigation Of The Effect Of The Velocity Ratio On The Flow And Wall Heat Transfer Characteristics Of A Wall-Bounded Dual Jet, Paula J. Murphy, Sajad Alimohammadi, Séamus M. O'Shaughnessy

Research Outputs: 2025-Present

A wall-bounded dual jet, consisting of a wall jet and a co-flowing offset jet, possesses a complex flow structure that has proved advantageous across many industrial applications. Despite this, dual jets remain relatively unexplored through experimentation and their flow phenomena are largely misunderstood. This investigation is the first to examine the effect of varying the velocity ratio (Vr) on the flow and heat transfer behaviour of a dual jet through experimental means. A velocity ratio range of 0.5≤Vr≤2 is achieved by varying each jet Reynolds number (Rew/o) in the range 5500≤Rew/o≤12,000. Infrared …

Hydrothermal Behavior Of A Novel Conical Twisted Strip Turbulator In A Heated Tube: A Numerical Analysis, Azher M. Abed, Bhavesh Kanabar, T. Ramachandran, Aman Shankhyan, Jasgurpreet Singh Chohan, A. Karthikeyan, Deepak Gupta, Bashir Salah, Waqas Saleem Jan 2025

Hydrothermal Behavior Of A Novel Conical Twisted Strip Turbulator In A Heated Tube: A Numerical Analysis, Azher M. Abed, Bhavesh Kanabar, T. Ramachandran, Aman Shankhyan, Jasgurpreet Singh Chohan, A. Karthikeyan, Deepak Gupta, Bashir Salah, Waqas Saleem

Research Outputs: 2025-Present

The increasing use of heated pipes and heat exchangers has created a pressing need to enhance thermal efficiency. This research introduces a novel turbulator design known as the conical twisted strip turbulator. The turbulator design resembles a cone and is composed of several twisted strip tentacles. This unique configuration is expected to generate strong rotational and radial flow patterns, leading to enhanced heat transfer. A numerical analysis was conducted using the RNG k-epsilon model to investigate various geometric parameters of the turbulator. The study examined the twisted angle, which varied from 60 to 270°, the number of twisted strip tentacles, …

Aspen Plus Modelling Of The Milena Dual Fluidised Bed Biomass Gasifier Technology, Mohadeseh Naderi, Hamid Rashidi, Anthony Reynolds, Wayne Doherty Jan 2025

Aspen Plus Modelling Of The Milena Dual Fluidised Bed Biomass Gasifier Technology, Mohadeseh Naderi, Hamid Rashidi, Anthony Reynolds, Wayne Doherty

Research Outputs: 2025-Present

The Energy Research Centre of The Netherlands is developing MILENA gasification technology to convert biomass fuels into high-value gaseous and liquid products. MILENA is a steam-blown dual fluidised bed (DFB) gasification process with separate gasification and combustion zones. This DFB gasifier produces high-quality gas with low N2 content suitable for vehicle fuel or natural gas grid injection. This study presents a semi-kinetic Aspen Plus model for MILENA gasification, including stages like drying, rapid pyrolysis, gasification, combustion, and tar cracking and reforming. Pyrolysis as a key step, was modelled using experimental data for the rapid pyrolysis of wood to calculate …

Bioinspired Gradient Porous Hip Implant Design To Prevent Stress Shielding Using Stress Mapping And Bone Remodeling Theory, Babak Ziaie, Xavier Velay, Waqas Saleem Jan 2025

Bioinspired Gradient Porous Hip Implant Design To Prevent Stress Shielding Using Stress Mapping And Bone Remodeling Theory, Babak Ziaie, Xavier Velay, Waqas Saleem

Research Outputs: 2025-Present

Total Hip Arthroplasty (THA) is a widely performed surgical procedure, with increasing frequency worldwide. Despite its high success rate, many patients require revision surgeries due to complications such as aseptic loosening, primarily resulting from stress shielding, cortical hypertrophy, and micromotion. These issues often stem from a mechanical mismatch between the bone and the solid dense implant, particularly a mismatch in stiffness. A potential solution lies in the use of porous or lattice structures in implant design, which offer lower stiffness and improved biocompatibility by facilitating bone ingrowth, cell seeding, and vascularization. Among these designs, Triply Periodic Minimal Surfaces (TPMS), especially …
