Study on the effect of temperature on deposition of virus fine particles by thermophoresis
Novel coronaviruses can attach to other substances to become composite particles and do damage to the human body.The deposition characteristics of thermophoresis were obtained by calculations under different ambient temperatures and human body temperatures.Under the same conditions of only considering the thermophilic effect,the higher the temperature difference between air and airway wall,the higher the thermophilic speed of virus particles,and the easier they are deposited in the respiratory tract and alveoli;the higher the ambient temperature and the lower the body temperature,the higher the deposition rate of virus particles,By calculating the characteristics of deposition in different ambient temperature and human body temperature,but under the same conditions considering only thermophoretic effects,we result that:the higher the temperature of air than the wall of air duct is,the higher the thermal swimming speed of virus particles is,and it is easier to deposit in the respiratory tract and alveoli;the higher the ambient temperature is and the lower the body temperature is,the higher the deposition rate of virus particles is,the easier it is to infect people with novel coronavirus and enhance the effect of virus;the lower the ambient temperature is and the higher the body temperature is,the virus particles may be affected by anthermophoretic force during transportation,thus preventing the deposition of virus particles in the human body.Humans may be more susceptible to the virus in the spring and summer when their body temperature drops.
