Nuclear fusion and bernouilli's principle

In summary, the conversation discusses the possibility of using Bernouilli's principle to cause nuclear fusion. The idea is to use funnel shaped targets instead of spherical ones, with lasers striking the wide ends of the funnels to force deuterium into the narrower parts where it would pick up speed. However, the physicist in the conversation argues that this approach would not work as Bernouilli's principle states that higher speed leads to lower pressure, while nuclear fusion requires high pressure and stagnant deuterium. Therefore, the idea of using Bernouilli's principle for fusion is not feasible.

Could Bernouilli's principle be used to cause nuclear fusion.Instead of spherical targets for lasers to strike what if we had funnel shaped targets - lots of them - with their apices all meeting in roughly the same region of space.Lasers beams could strike the wide ends of the funnels and force deuterium into the narrower parts of the funnels where it would pick up speed. Or would there be too much back pressure?

Rothiemurchus,

You don't want to have the deuterium pick up speed. Recall Bernoulli's Principle states that
the faster the material moves - the LOWER the pressure. You don't want fast moving LOW
pressure deuterium.

You want to have HIGH pressure STAGNANT deuterium. That's what a spherical implosion
gives you. Forget Bernoulli.

While Bernoulli's principle can be used to explain the behavior of fluids, it cannot be directly applied to cause nuclear fusion. This principle states that as the speed of a fluid increases, its pressure decreases. However, nuclear fusion requires extremely high temperatures and pressures, much higher than what can be achieved through the application of Bernoulli's principle.

Using funnel shaped targets instead of spherical targets for lasers to strike may not necessarily increase the chances of achieving nuclear fusion. In fact, the shape of the target does not play a significant role in the fusion process. The key factor is the intense heat and pressure generated by the lasers, which can be achieved with both spherical and funnel shaped targets.

Moreover, the concept of using multiple funnel shaped targets with their apices meeting in the same region of space may not be feasible. This would require precise alignment and coordination of all the targets, which may not be achievable in practice. Additionally, the back pressure generated by the lasers may not be a major concern as it can be controlled and managed in the design of the fusion process.

In conclusion, while Bernoulli's principle can help us understand the behavior of fluids, it cannot be directly applied to cause nuclear fusion. The shape of the target and the use of multiple targets may not significantly impact the likelihood of achieving fusion, as the key factors are the intense heat and pressure generated by the lasers. Further research and experimentation are needed to develop effective methods for achieving nuclear fusion.
 

Related to Nuclear fusion and bernouilli's principle

1. What is nuclear fusion?

Nuclear fusion is the process by which two or more atomic nuclei combine to form a heavier nucleus, releasing a large amount of energy in the process. This is the same process that powers the sun and other stars.

2. How is Bernoulli's principle related to nuclear fusion?

Bernoulli's principle states that as the velocity of a fluid increases, the pressure decreases. In the case of nuclear fusion, the intense heat and pressure generated by the fusion reaction causes the particles to move at high speeds, resulting in a decrease in pressure. This principle is important in containing and controlling the fusion reaction.

3. What are the potential benefits of nuclear fusion?

If harnessed successfully, nuclear fusion could provide a virtually limitless source of clean energy. It produces no greenhouse gas emissions and does not produce long-lived radioactive waste like nuclear fission does.

4. What are the challenges of achieving nuclear fusion?

Nuclear fusion requires extremely high temperatures and pressures to overcome the repulsive forces between atomic nuclei. Containing and controlling the reaction is also a major challenge. Additionally, the materials used to contain the reaction must be able to withstand extreme heat and radiation without degrading.

5. Is nuclear fusion currently being used to generate energy?

While nuclear fusion has been achieved in experimental settings, it has not yet been successfully harnessed for practical energy production. Scientists and engineers continue to work on developing and improving fusion reactors, but it is not yet a commercially viable source of energy.
