Hello, I am Reazwan
First Class BEng (Hons) Mechanical Engineering graduate with hands-on experience in automotive systems, fluid dynamics, and machine design, with a focus on design and simulation.
Skilled in FEA (ANSYS Workbench), CFD (ANSYS Fluent), parametric 3D modelling (CSWP certified SolidWorks), FDM 3D printing, and microcontroller integration (Arduino/ESP32), with a strong track record of delivering technical solutions from concept to physical prototype.
I welcome connections with professionals passionate about mechanical design, product development, and simulation.
Portfolio Projects & Designs
Steering Knuckle Design
Redesigned a JLR rear suspension knuckle from cast steel to A356 aluminium — ~66% weight reduction. Validated with static and frequency-response FEA in ANSYS. Max stress at 13% of yield, FoS above 5. Led DFMEA across a five-person team.
Dissertation: Tennis Ball Launcher
Designed, manufactured and tested a dual-wheel BLDC launcher exploiting the Magnus effect within a £300 budget. Modelled in SolidWorks, FDM-printed in PETG. Custom 4:1 planetary gearbox delivering 1.62 Nm torque, validated at 30–40 mph.
Submarine CFD Analysis
Steady-state RANS CFD of a full-scale submarine at 20 km/h using Ansys Fluent. 6.27M-element mesh; drag converged to ~33,500 N. Stagnation pressure matched theory within 0.03%. Conning tower identified as primary drag source.
IMechE Design Challenge
Led a six-engineer team to design an autonomous wall-impact return vehicle for IMechE 2023–24. Rack-and-pinion distance measurement with motor polarity reversal — zero post-activation intervention, within a £40 budget.
Portable Gantry Crane
Designed and FEA-validated a portable gantry crane to BS EN 1991/1993. Bending stress 1.40 MPa (FoS = 253), deflection 0.014 mm (FoS = 167). ANSYS FEA validated within 1%. Modal analysis confirmed no resonance risk. Drawings to BS 8888.
Wind Tunnel
Designed and built a wind tunnel using 3D-printed components, 12V DC fans, and ultrasonic misters. Arduino and ESP32 for real-time control; results validated with ANSYS/SolidWorks CFD simulations to analyse aerodynamic performance.
My Expertise
3D Modeling
Proficient in parametric CAD and full assembly modelling with SolidWorks (CSWP certified) and Autodesk Fusion. Experienced in creating simulation-ready geometry for FEA and CFD analysis, engineering drawings in accordance with BS 8888, design-for-manufacture (DFM), and mould design for functional prototypes.
Electronics & Embedded Systems
Skilled in circuit design (PCB/breadboard), embedded programming (C++, MicroPython, Python), and prototyping with Arduino/ESP32. Experienced in IoT, sensor systems, and firmware development for real-world applications.
Machine Operation
Proficient in subtractive and additive manufacturing processes, such as CNC machining (3-5 axis milling/drilling), laser cutting/engraving, and additive manufacturing (FDM, resin, SLS). CSWA-AM Certified. Basic experience in sheet metal fabrication, including forming, bending, and designing for manufacturing.
