Discussion Overview
The discussion revolves around calculating the oblique shock angle (beta) for a supersonic airfoil using MATLAB. Participants are exploring methods to derive this angle based on parameters such as angle of attack, Mach number, and airfoil geometry. The conversation includes technical challenges related to the implementation of the calculation in MATLAB and alternative software options.
Discussion Character
- Technical explanation
- Mathematical reasoning
- Debate/contested
Main Points Raised
- One participant is seeking an equation to calculate the oblique shock angle (beta) and expresses difficulty in finding a suitable formula.
- Another participant suggests using MATLAB to solve for beta and mentions having the relevant equation in a textbook.
- Some participants note that the equation for beta is complex and may be split into multiple parts, complicating the calculation.
- There are suggestions to use numerical methods such as iteration or MATLAB's fsolve command to find beta, indicating a preference for numerical solutions over symbolic ones.
- Participants express varying opinions on software tools, with some advocating for Maple while others prefer Mathematica, highlighting a debate on the best computational tools for this task.
- A later post reiterates the initial request for help with the MATLAB program, indicating ongoing interest in collaboration or assistance.
Areas of Agreement / Disagreement
Participants do not reach a consensus on the best method to calculate the oblique shock angle, with multiple approaches and software preferences being discussed. The complexity of the equations involved and the lack of a straightforward solution contribute to the unresolved nature of the discussion.
Contextual Notes
Participants mention the absence of the symbolic math toolbox in MATLAB as a limitation, which affects their ability to solve the equation for beta directly. The discussion also reflects varying levels of familiarity with different computational tools and their capabilities.
