🔍 Key Concepts

• Roots blower design and how lobe shape (helical vs cylindrical) affects airflow smoothness • Effect of number of lobes on pulsation frequency and air delivery uniformity • Why turbulence and pulsation are undesirable in scavenging air systems for two-stroke medium-speed diesels

💭 Think About

• Compare how airflow would look if lobes mesh gradually versus mesh all at once—which design gives a smoother handoff of air? • Think about how more lobes vs fewer lobes changes how often discharge pulses occur per revolution—does that make flow smoother or rougher? • Between helical and cylindrical profiles, which one is more likely to reduce sharp pressure spikes and sudden volume changes?

✅ Before You Answer

• Identify which options are helical and which are cylindrical—separate shape from lobe count first • For each option, imagine the number of discharge events per revolution and how that affects pulsation • Ask: which combination of lobe shape and lobe count is most likely to create a nearly continuous, smooth airflow with minimal turbulence?
