Simulation Consultants
Accuracy is never left to chance
jimmylea’s simulation consultants deliver advanced simulation analysis services to clients across Australia and Singapore. We provide professional expertise in computational fluid dynamics (CFD), multiphase flow simulation, process dynamics simulation, and reactive process simulation.
Using industry-leading tools like ANSYS Fluent, we model multiphase flow, multispecies transport, multiphysics phenomena, combustion, reaction chemistry, advanced chemical processes, and more. But we never stop at raw outputs.
Simulation without industry insight leads to misleading outcomes
We understand that unguided or misinterpreted simulations can produce misleading results, leading to poor decisions, operational risks, or costly rework. At jimmylea, every analysis is backed by in-house plant engineering design and process engineering expertise. This ensures recommendations are not only technically precise but practically viable and ready for implementation.
Our simulation work targets the chemical, energy, resources, and water industries, sectors with complex fluids, high-risk operating conditions, tight regulatory requirements, and intricate physics. By specialising exclusively in these fluid-centric sectors, we deeply understand the nuances of complex fluid behaviour and provide truly industry-specific interpretation, delivering recommendations and solutions grounded in sector-specific insight and real-world constraints. These environments demand more than software proficiency: they require deep understanding of process behaviour, engineering constraints, and real-world application.
More than outputs but clear, outcome-driven recommendations
When you engage jimmylea, you gain more than simulation results. You partner with a team that has the technical depth to interpret complex data, integrate industry-specific insight, and translate findings into practical, actionable recommendations that solve real problems and drive confident decisions.
With over 50 years of combined experience, our consultants deliver practical insights that minimise risks, optimise performance, reduce downtime and costs, and support sustainable, resilient operations.
When you choose jimmylea, you get simulation backed by engineering judgment, trusted by clients across Sydney, Melbourne, Brisbane, Perth, and Singapore.

Multiphase Flow Simulation
We offer professional consultancy services for the analysis and simulation of multiphase flow systems and pipe networks involving gas, liquid and solid phases. Our goal is to understand and optimise complex flow behaviour to support reliable, efficient and fit-for-purpose process and equipment design. With our expertise in fluid dynamics and chemical engineering, we analyse challenges such as phase distribution, solids suspension, particle transport, pressure drop, flow distribution and complex flow behaviour. Whether you are developing new equipment, designing a pipe network, optimising an existing process or troubleshooting operational problems, we provide practical engineering analysis tailored to your specific requirements. Our multiphase flow simulation services include:
- Gas-liquid and liquid-solid flow analysis: evaluate phase distribution and flow behaviour
- Solids suspension and particle transport: predict suspension, deposition and distribution
- Bubble and droplet behaviour: analyse dispersion, coalescence, breakup and interaction
- Pipe network analysis: evaluate single and multi-loop networks, flow distribution and pressure drop
- Pump and system analysis: determine pump requirements, flow rate and system head
- Flow troubleshooting: investigate maldistribution, cavitation, surges, settling and blockages

Process Dynamics Simulation
Our engineers perform advanced modelling of reactive and dynamic process systems to evaluate how chemical reactions, heat and mass transfer, and multiphase flow interact under real operating conditions. These studies enable accurate prediction of process performance, stability, and safety margins across continuous and batch operations.
- Chemical industry: designing, optimising or troubleshooting chemical process plants
- Energy sector: improving operational performance, safety, and stability in oil and gas facilities
- Resources industry: enhancing reliability, efficiency in mineral processing operations
- Water industry: designing and optimising wastewater treatment and water purification systems
Through process dynamics simulation, we enable clients to minimise risks, increase operational efficiency, and deliver measurable economic improvements. By proactively identifying potential issues and optimising plant performance, our approach helps clients reduce downtime, maintenance costs, and resource consumption, ensuring resilient and sustainable operations.
