Fluid Dynamics Engineer

About the role:

Responsible for designing and analyzing pressurized airflow, piping, nozzle, and spray/dispersion systems to support Cloud Generator development and Weather Modification processes. The primary focus is conducting fluid flow calculations and simulations to determine air pressure requirements, flow rate, pipe configuration, nozzle configuration, and outlet flow characteristics to achieve spray targets up to 1 km altitude.

Key responsibilities:

• Design pressurized airflow, piping, and nozzle system concepts based on target flow rate, pressure, and spray altitude.
• Conduct fluid flow calculations and simulations to analyze pressure, velocity, flow rate, pressure drop, and flow distribution within piping systems.
• Determine pipe dimensions, piping configuration, nozzle specifications, and operating parameters based on calculation and simulation results.
• Analyze airflow discharge from nozzles, including jet/spray trajectory, dispersion, and factors affecting the ability to reach target altitude up to 1 km.
• Optimize pressure, flow rate, nozzle configuration, and airflow path to achieve target spray/dispersion.
• Support analysis and design of mixing/injection systems for aerosol and water vapor according to process requirements.
• Validate designs through prototype testing and compare calculation and simulation results with actual measurements.
• Provide design optimization recommendations based on simulation and testing results and support integration with engineering teams.
• Prepare engineering calculations, simulation results, design recommendations, and technical reports.

Requirements:

• Minimum Bachelor's degree, preferably Master's degree, in Mechanical Engineering, Chemical Engineering, Aerospace Engineering, Physics, or related field.
• Relevant work experience or project/research experience in fluid dynamics, fluid flow analysis, piping systems, nozzle/spray systems, or related fields.
• Understanding of pressurized flow, internal pipe flow, pressure drop, flow distribution, jet flow, and fluid discharge concepts.
• Experience using CFD or engineering simulation tools for fluid flow analysis.
• Ability to conduct engineering calculations, simulation interpretation, and technical analysis.
• Prototype testing and design validation experience is an added value.
• Strong analytical thinking, problem-solving, and technical communication skills.
