Best Gemini prompts for Mechanical Engineers

Given a CAD model of a heat exchanger with the following specifications: inlet temperature 80°C, outlet temperature 40°C, flow rate 0.1 kg/s, and a desired pressure drop of 10 kPa, use computational fluid dynamics to optimize the fin geometry and tube arrangement for maximum heat transfer coefficient while minimizing material usage. Assume a Reynolds number of 1000 and a Prandtl number of 0.7. Provide a detailed report including contour plots of temperature and velocity distributions, as well as a table summarizing the optimized design parameters.

Analyze the vibration data from a centrifugal pump that has been experiencing premature failure, with the following characteristics: flow rate 50 m³/h, head 50 m, speed 1800 rpm, and a vibration amplitude of 2 mm/s. Using Fourier analysis and machine learning algorithms, identify the most likely cause of failure (e.g. imbalance, misalignment, bearing wear) and provide a recommendations for corrective action, including a prioritized list of potential solutions and a detailed report of the analysis methodology.

Create a simulation model of a mechanical system consisting of a motor, gear train, and load, with the following requirements: motor torque 10 Nm, gear ratio 3:1, load inertia 0.1 kg m², and a desired settling time of 1 second. Using a physics-based modeling approach, design and optimize the system parameters (e.g. motor size, gear tooth profile, damping coefficient) to meet the performance requirements while minimizing energy consumption. Provide a detailed report including time-domain plots of position, velocity, and torque, as well as a table summarizing the optimized design parameters.

Develop a predictive maintenance model for a fleet of industrial pumps using a dataset of historical sensor readings (e.g. pressure, flow rate, temperature, vibration) and maintenance records. Using machine learning algorithms and statistical analysis, identify the most relevant features and predictors of equipment failure, and provide a set of recommendations for maintenance scheduling and resource allocation, including a prioritized list of equipment at risk of failure and a detailed report of the model methodology and performance metrics.
