In summary: While there is no specific software to calculate these values, there are resources available that can help guide your experimental process. In summary, the optimal values for peak voltage, peak current, and frequency of applied pulses in a pulsed streamer discharge in liquids will vary and should be determined through experimentation, while the optimal configuration of electrodes should also be determined experimentally for each specific sample. There is no specific software to calculate these values, but there are resources available to guide the experimentation process.

i am working on pulsed streamer discharge in liquids and specifically in water as my master project. at this time i am designing my pulse generator and reactor. i have a question about reactor design and specifically about the electrode design and distance between them:
i want to know for a liquid like wastewater or water itself which is supposed to be treated between electrodes in the reactor, how much should be the peak voltage, peak current and frequency of applied pulsed to the electrodes to guarantee streamer discharge?and also is there any relationship between electrodes configuration(distance of electrodes and shape) and mentioned values( peak voltage, peak current and frequency of applied pulsed)?
is there any software to calculate these values or at least help to calculate them?

Unfortunately, there is no single answer to your question as the optimal peak voltage, peak current, and frequency of applied pulses will depend on the specific wastewater or water sample you are working with. The best way to determine the optimal values is to experimentally test different combinations of voltage, current, and frequency to see which one produces the most efficient streamer discharge. Additionally, the optimal configuration of the electrodes (distance between them and shape) will also depend on the specific sample being used, so it is best to experimentally test different configurations to determine which one will produce the most efficient results.
 

FAQ: Pulsed Streamer Discharge in Liquids: Voltage, Current & Frequency

What is a pulsed streamer discharge in liquids?

A pulsed streamer discharge in liquids is a phenomenon where an electrical discharge occurs in a liquid medium due to the application of high voltage pulses. It involves the formation and propagation of plasma channels in the liquid, which results in the production of various reactive species and can be used for various applications such as wastewater treatment and surface modification.

What is the role of voltage in pulsed streamer discharge in liquids?

Voltage plays a crucial role in pulsed streamer discharge in liquids as it is the driving force behind the formation and propagation of plasma channels. Higher voltages can generate longer and more stable plasma channels, resulting in a more efficient discharge. However, too high voltages can also lead to overheating and damage to the liquid medium.

How does the current affect pulsed streamer discharge in liquids?

The current is another important factor in pulsed streamer discharge in liquids as it determines the amount of energy delivered to the liquid. Higher currents can result in a more intense discharge, leading to a higher production of reactive species. However, excessive currents can also cause arcing and damage to the liquid medium.

What is the significance of frequency in pulsed streamer discharge in liquids?

The frequency of the applied voltage pulses affects the discharge in two ways. Firstly, it determines the duration of the plasma channels, with higher frequencies resulting in shorter channels. Secondly, it affects the energy distribution within the plasma channels, with lower frequencies leading to a more homogenous energy distribution. This can impact the efficiency and selectivity of the discharge process.

What are the applications of pulsed streamer discharge in liquids?

Pulsed streamer discharge in liquids has a wide range of applications, including wastewater treatment, surface modification, and material synthesis. It can also be used for plasma medicine, where the reactive species produced can be used for targeted cancer treatment and wound healing. Additionally, it has potential applications in environmental remediation and food processing.
