Welcome to the Assessment- Flow Around a Circular Stationary Cylinder!
This assessment is designed to evaluate your understanding of the core concepts related to how aerodynamic coefficients evolve with changes in the angle of attack, and the Simscale simulation you have attempted.
Assessment Instructions:
1. Time Allowance: You are encouraged to take your time to carefully consider each question before providing your response.
2. Single Attempt: Please note that you have one attempt to complete this assessment. Ensure that your answers are final before submission.
3. Evaluation: Your responses will be recorded and thoroughly evaluated. Detailed feedback will be provided to help you understand your performance.
4. Results/Final Score: Once every student in the class has completed the assessment, you will be informed of your results and grades in the class.
Thank you for your dedication to learning and best of luck with your assessment!
