A progressively severe sore throat on one side and pain during swallowing (odynophagia) usually are the earliest symptoms. As the abscess develops, persistent pain in the peritonsillar area, fever , a general sense of feeling unwell , headache, and a distortion of vowels informally known as "hot potato voice" may appear.
As bow shocks occur for high flow deflection angles, they are often seen forming around blunt bodies, because of the high deflection angle that the body impose to the flow around it. The thermodynamic transformation across a bow shock is non-isentropic and the shock decreases the flow velocity from supersonic velocity upstream to subsonic ...
For air with a heat capacity ratio =, then =; other gases have in the range 1.09 (e.g. butane) to 1.67 (monatomic gases), so the critical pressure ratio varies in the range < / <, which means that, depending on the gas, choked flow usually occurs when the downstream static pressure drops to below 0.487 to 0.587 times the absolute pressure in ...
It is a very serious disorder of the back of the throat near the windpipe. The most common cause of epiglottitis is an infection by the bacteria, H influenza. The condition may present all of a sudden with high fever, severe sore throat, difficult and painful swallowing, drooling saliva, hoarse voice, difficulty breathing and malaise. The ...
It is not known whether antibiotics are effective for preventing recurrent sore throat. [14] There is only limited evidence that a hot drink can help alleviate a sore throat, and other common cold and influenza symptoms. [15] If the sore throat is unrelated to a cold and is caused by, for example, tonsillitis, a cold drink may be helpful. [16]
As the pressure is reduced still further, a pressure is reached that result in M = 1 at the throat with subsonic flow throughout the remainder of the nozzle. There is another receiver pressure substantially below that of curve C that also results in isentropic flow throughout the nozzle, represented by curve D; after the throat the flow is ...
A case of strep throat. Streptococcal pharyngitis or strep throat is caused by a group A beta-hemolytic streptococcus (GAS). [20] It is the most common bacterial cause of cases of pharyngitis (15–30%). [19] Common symptoms include fever, sore throat, and large lymph nodes. It is a contagious infection, spread by close contact with an infected ...
Laryngopharyngeal reflux (LPR) or laryngopharyngeal reflux disease (LPRD) is the retrograde flow of gastric contents into the larynx, oropharynx and/or the nasopharynx. [4] [5] LPR causes respiratory symptoms such as cough and wheezing [6] and is often associated with head and neck complaints such as dysphonia, globus pharyngis, and dysphagia. [7]
